Riding After Hip Replacement: Why Deb Chose the Relaxed Body E-Bike

Four E-Bikes, One Rider, and a Recovering Hip

Some of the most useful bike reviews we ever get don't come from me. They come from riders who walk into our store with a real problem to solve and ride everything until one bike solves it. Deb is a perfect example.

Deb had recently had hip replacement surgery. She was still recovering, and part of that recovery was building up the muscles around the new hip so they could support it. She wasn't shopping for speed or for a bike that looked good parked outside a café. She needed something her body could actually live with, ride after ride, while it healed and got stronger.

So she rode four bikes in one visit:

• The Relaxed Body E-Bike 26" 500W Deluxe
• The Relaxed Body 20" with Office Chair seat
• The Simple Step-Thru 20" 500W Deluxe
• The Simple Step-Thru 750W Fat Tire Deluxe

All four sit in our comfort electric bike lineup, and all four share the low, easy-to-mount frames we build our reputation on. On paper, any of them could have been the right answer. Deb picked the Relaxed Body E-Bike, and she didn't hesitate when she explained why.

What Deb said, in her own words

"This one felt the most comfortable because the pedals are in a forward position, which enables me to stretch my legs right out," she told us. She also pointed out that "you sit in a very upright position," and that the combination was easy on her shoulders, hips, knees, and every other joint she could name. She even called out her wrists, crediting the position of the handlebars.

That's a short testimonial, but there's a lot packed into it. Deb named three separate things, and each one maps to a real design decision on the bike:

• Leg extension. Forward pedals let her straighten her legs fully on each stroke instead of pedaling with her knees and hips folded up.
• Upright posture. Sitting tall keeps her weight on the seat rather than leaning forward onto her hands and lower back.
• Handlebar position. Bars that come back toward the rider let the arms rest at a natural angle, which takes strain off wrists and shoulders.

If you're dealing with a joint replacement, arthritis, back trouble, or just a body that doesn't love a traditional bike anymore, those three things are exactly what you should be testing for. Deb did my job for me. She went straight to the questions that matter.

A quick word before we go further

I fit people to bikes for a living. I'm not a surgeon or a physical therapist, and nothing in this article is medical advice. If you're recovering from a hip replacement or any other surgery, talk to your care team about when you can start riding, how much, and what kind of motion they want you to avoid. What I can do is explain how these bikes are built, why Deb's pick worked for her, and how each of the other three might fit a different rider.

Here's how the rest of this piece is laid out. First, I'll go deep on the Relaxed Body E-Bike, the bike Deb chose. Then I'll give each of the other three bikes its own section so you can see where it shines. After that, I'll compare all four on the features that matter most for joint comfort, and I'll finish with practical advice on fit, test rides, and getting started. If you already know you're a comfort-first rider, our e-bikes for seniors collection is a good place to browse alongside this article, since many of the same priorities apply.

The Relaxed Body E-Bike is the bike that won Deb over, so let's start with what makes it different from a standard e-bike. The short answer is the frame. Almost everything Deb loved about the ride traces back to the geometry.

A semi-recumbent position without a recumbent bike

We describe the Relaxed Body as a semi-recumbent e-bike. You're not lying back like you would on a full recumbent, but you're not perched over the pedals like on a road bike either. The seat sits in a slightly reclined position that supports your back, and the pedals are moved forward, out in front of your body.

That forward pedal placement is the detail Deb noticed first. On a traditional bike, the pedals sit almost directly under the seat. To get full leg extension, you have to raise the seat, which means you're sitting higher off the ground and your feet can't reach the pavement easily when you stop. On the Relaxed Body, moving the pedals forward lets you keep the seat low and still straighten your legs on every stroke.

For Deb, that mattered twice. The long, open leg motion felt good on a joint she was actively rehabbing. And the low seat meant she could put her feet down flat at a stop without tipping or stretching.

Upright posture and the handlebar setup

The second thing Deb mentioned was sitting "very upright." The Relaxed Body uses what we call relaxed body geometry: your torso stays tall, your weight rests on the seat, and you're not leaning forward onto your hands. Our aluminum Comfort Performance Steer handlebar sweeps back toward the rider, so your arms can rest at a comfortable angle instead of reaching.

That's why Deb said the bike was easy on her shoulders and wrists. When your bars are too far forward or too low, your upper body ends up holding you up. On this bike, the seat does that job.

Getting on and off

The frame has an ultra-low step-over height. You don't swing a leg up and over a top tube; you step through the frame, sit down, and go. For anyone protecting a hip, that's not a small thing. Lifting a leg high and sideways is exactly the kind of movement that can feel awkward after hip surgery, and this frame is designed so you don't have to make it.

Motor, throttle, and speed

The Relaxed Body runs a 48V 500W rear hub motor. It uses a cadence-style setup rather than a torque sensor, so the assist comes on consistently when you pedal instead of scaling with how hard you push. For a rider who's still building strength, that's helpful: you get steady help without having to muscle the pedals to wake the motor up.

There's also a thumb throttle on the left grip. Press it, and the motor moves you without pedaling at all. You can ride up to 20 mph using either pedal assist or the throttle. In practice, that means you decide how much work your legs do on any given day. If your physical therapist wants you pedaling, you pedal. If you're tired on the way home, the throttle is right there.

Comfort hardware

The current Deluxe version added a steel front suspension fork, which soaks up road cracks and bumps before they reach your hands, shoulders, and back. It rolls on 26" x 2.125" tires, and the oversized Comfort Contour seat is packed with soft foam. The synthetic leather grips are soft, too, which helps with the wrist comfort Deb noticed.

The rest of the spec sheet

Here are the remaining details worth knowing:

• Battery: 48V 14Ah lithium, with a range of up to 50 miles depending on how much you use assist versus throttle.
• Brakes: Tektro mechanical disc brakes front and rear with 160mm rotors.
• Gearing: Shimano Tourney 7-speed, so you can pick an easy gear for starts and hills.
• Lights: Integrated front and rear lights, so there's nothing to clip on or forget.
• Display: Shows speed, battery level, and the pedal assist level you're in.
• Frame: 13" aluminum, with steel fenders.

Who the Relaxed Body is for

This bike makes the most sense for riders who want maximum leg extension with a low seat, an upright and slightly reclined position, and an easy step-through frame. That describes a lot of people dealing with hip, knee, or back pain. Our fit data for this model lists it as good for riders with knee and/or back pain, and Deb's experience lines up with that.

If you're browsing for more bikes built on the same priorities, our full step-thru electric bike collection is worth a look, since a low step-through frame is the foundation of every comfort-first design we make.

If the semi-recumbent idea appeals to you but you want even more back support, the Relaxed Body 20" with Office Chair seat takes that concept further. It's one of the more unusual bikes we make, and it's the one people tend to stare at first when they walk into the store.

The seat is the whole point

Instead of a saddle, this bike has a high-back seat styled after an office chair, with a large, extra-cushy seat pad. The backrest supports your lower and mid back while you ride, and the seat slides forward and back so you can dial in the distance to the pedals for your body.

That support changes how the ride feels. On a saddle, your core is doing at least some of the work of holding you up. In this seat, you can lean back and let the chair carry that load, which is a big deal for riders whose backs get tired or sore on a conventional bike.

Forward pedals and a low ride height

Like its 26" sibling, this bike uses a forward pedaling design that puts the pedals out in front of your body. Combined with the 20" wheels, it keeps you close to the ground. A low step-over height makes mounting and dismounting simple: step in, sit back, and you're set.

Being closer to the ground also helps with confidence at stops. Your feet reach the pavement easily, and the low center of gravity from the smaller wheels makes the bike easy to balance at slow speeds.

More motor

This model steps up to a 48V 750W rear-mounted motor. You can ride under pedal assist or use the twist throttle to cruise without pedaling. The extra power is useful for hills and for heavier riders. The bike is rated for riders up to 350 lbs.

One detail worth testing in person: this is a twist throttle, so you rotate your wrist to engage it. Most riders find that natural. If your wrists or hands are sensitive, though, spend a few minutes on the throttle during your test ride to make sure it feels good.

Tires, battery, and adjustability

• Tires: 20" x 3" slick tread, giving a wide, stable base on pavement and hard-packed trails.
• Battery: 48V 14Ah lithium with up to 50 miles of range, depending on rider weight, terrain, and how much you use the motor. The battery tucks inside the frame and pops out for charging indoors.
• Handlebars: Mini ape hanger style bars that tilt and raise or lower, so it's easy to find the right reach for your arms.
• Brakes: Front and rear mechanical disc brakes.
• Display: A full color display showing speed, battery level, and power level.
• Lights: LED headlight and taillight.

The spec sheet lists a steel fork on this model rather than a suspension fork, so most of the cushioning comes from those wide 3" tires and the padded chair seat. On smooth paths and neighborhood streets, that's plenty for most riders.

Who the Office Chair model is for

This is the bike for riders who want back support above everything else. If your lower back is the first thing to complain on a bike, or you simply want to sit back and cruise like you're in a favorite chair, this is the one to try. It's also a strong pick for heavier riders who want the extra power and the 350 lb rating.

If seating is your top priority, you can also browse our sixthreezero seats to see the comfort saddles and seating options we offer across the lineup.

The Simple Step-Thru 20" is the compact option in this group. It's built around a very low step-through frame and small 20" wheels, and it's designed for riders who want something easy to handle, easy to store, and easy to get on and off.

Low frame, upright ride

The headline feature is the step-through height. The frame sits low enough that you can walk into it rather than climbing over it, which makes mounting and dismounting simple for riders of all ages and abilities. Once you're on, the upright riding position keeps pressure off your back and shoulders.

The 20" wheels keep the bike nimble. It turns easily, handles well in tight spaces like bike lanes, driveways, and apartment complexes, and feels manageable at walking speed. For riders who get nervous on a tall bike, that low, compact feel is a big part of the appeal.

Smoother than before

The current Deluxe version added a steel front suspension fork. Small wheels can feel bumps more than larger ones, so the suspension makes a noticeable difference on rough pavement and cracked sidewalks. It also has integrated front and rear lights, so you're visible on early morning and evening rides without any extra setup.

Motor and battery

The Simple Step-Thru 20" runs a 48V 500W rear hub motor. You can use pedal assist when you want a little boost, or the throttle when you want the motor to do the work, with a top speed of up to 20 mph. The 48V 10.4Ah lithium battery is rated for up to 50 miles of range on a charge, depending on how you ride.

The rest of the build

• Brakes: Tektro mechanical disc brakes front and rear with 160mm rotors.
• Gearing: Shimano Tourney 7-speed derailleur with a Shimano shifter.
• Tires: 20" x 1.95" Wanda tires.
• Seat and grips: Our oversized Comfort Contour seat and soft synthetic leather grips.
• Frame: Aluminum alloy, with steel fenders.
• Display: Speed, battery level, and power level at a glance.

Fit and portability

Our fit chart for this model covers riders from 4'11" to 6'4" and up to 300 lbs, and it's listed as good for riders with knee and/or back pain. The compact size is a practical advantage, too. We designed it to be small enough to fit in many car trunks and back seats, which makes it easier to bring the bike to a flat, quiet path rather than riding from your front door.

Who the Simple Step-Thru 20" is for

This is a great fit for shorter riders, people with limited storage space, and anyone who wants a small, approachable e-bike that's easy to control. If you plan to transport your bike by car, or you live somewhere with tight hallways and elevators, the compact frame is a real advantage. It's also a friendly first e-bike for riders who haven't been on a bike in years and want something that feels manageable from day one.

The Simple Step-Thru 750W Fat Tire Deluxe is the most capable bike Deb rode that day. It keeps the easy-access frame that defines the Simple Step-Thru family, then adds more power, more range, and wide tires that can leave the pavement behind.

A low frame with forward pedals

We designed this frame with the lowest step-thru height we could, so there's no high top tube to swing a leg over. Getting on and off is easy, and the risk of tipping during a dismount drops way down.

It also uses a forward pedal design. The pedals sit roughly four inches farther forward than they would on a traditional bike frame. That lets you keep the seat low to the ground and still get good leg extension when you pedal, and it means you can put your feet down flat at a stop.

750 watts and up to 60 miles

This bike runs a 750W rear hub motor, which gives it more torque for steeper hills and rougher off-road terrain. You can use pedal assist to amplify your effort or the thumb throttle to ride under full electric power, with a top speed of 20 mph either way.

The 48V 14Ah lithium-ion battery is rated for up to 60 miles per charge, depending on how you ride. That extra range is useful for long recreational rides, or simply for charging less often.

Fat tires plus suspension

The 26" x 3" all-terrain tires add grip and cushioning on both pavement and hard-packed trails. Wide tires carry more air, so they absorb more of the bumps on their own. Pair them with the steel front suspension fork, and the bike smooths out uneven ground well, which is good news for your wrists, shoulders, and back.

The wide tires also add stability. The bike feels planted, especially on loose or uneven surfaces where a skinny tire might wander.

The rest of the build

• Brakes: Front and rear mechanical disc brakes.
• Gearing: Shimano Tourney 7-speed cassette with a Shimano Revo twist shifter.
• Frame: 18" aluminum step-thru with rear rack and fender mounts.
• Display: LCD showing speed, power level, and battery charge.
• Seat and grips: Extra-wide, soft foam saddle and synthetic leather grips.

Who the 750W Fat Tire is for

The ergonomic riding position on this bike is designed to reduce pressure on your wrists, shoulders, back, and knees, and our fit data lists it as good for riders with knee and/or back pain. It suits riders who want comfort and easy access but also want to ride hills, gravel paths, beach roads, or park trails. It's also a strong choice for heavier riders who want extra motor power.

If wide tires and all-terrain comfort sound like your priorities, our fat tire electric bikes collection has more options built around the same idea.

Now that you've seen each bike on its own, let's put them side by side on the features Deb cared about. When you're shopping with sore joints or a recovering hip, a few design details matter far more than top speed or color options.

Pedal position and leg extension

This was the deciding factor for Deb, so it goes first. Three of the four bikes use a forward pedal design. The Relaxed Body E-Bike and the Relaxed Body 20" both put the pedals out in front of your body in a semi-recumbent layout. The Simple Step-Thru 750W also moves the pedals forward, roughly four inches compared with a traditional frame. The Simple Step-Thru 20" is built around its compact frame and very low step-through height.

Why does this matter so much? Forward pedals let you keep the seat low while still straightening your legs on each stroke. You get a long, open pedal motion without perching high off the ground. For Deb, rebuilding the muscles around her hip, that full extension is what made the Relaxed Body feel right.

Seating and back support

The Relaxed Body 20" with Office Chair is in a class of its own here. Its high-back chair seat supports your back the whole ride. The Relaxed Body E-Bike puts you in a slightly reclined, upright position on a wide Comfort Contour seat. Both Simple Step-Thru models seat you upright on an oversized, soft saddle.

If back support is your single biggest need, try the Office Chair model. If you want upright and slightly reclined with more of a traditional bike feel, the Relaxed Body E-Bike is the middle ground Deb chose.

Getting on and off

All four bikes use low step-through or low step-over frames. None of them make you swing a leg high over a top tube. That's the baseline for every bike in our comfort lineup, and it's why all four were on Deb's list in the first place. The differences are in ride height: the 20" models sit lowest to the ground, while the forward-pedal designs let you keep the seat low on the larger bikes, too.

Handlebars and wrists

Deb specifically credited the Relaxed Body's handlebar position for taking strain off her wrists. All four bikes keep you upright, which naturally reduces the weight on your hands. The Office Chair model adds adjustable mini ape hanger bars that tilt and move up or down.

Throttle style is the other wrist consideration. The Relaxed Body E-Bike and the Simple Step-Thru 750W use a thumb throttle, which you press with your thumb. The Relaxed Body 20" uses a twist throttle, which you rotate with your wrist. Neither is better in general, but if your hands or wrists are sensitive, try both during your test ride.

Cushioning on rough surfaces

The Relaxed Body E-Bike, the Simple Step-Thru 20", and the Simple Step-Thru 750W all have front suspension forks. The 750W pairs its suspension with 3" fat tires, making it the most cushioned of the group on rough ground. The Office Chair model lists a steel fork and relies on its 3" tires and padded seat for comfort.

Power, range, and size

• Relaxed Body E-Bike 26": 500W, 48V 14Ah, up to 50 miles, 26" wheels.
• Relaxed Body 20" Office Chair: 750W, 48V 14Ah, up to 50 miles, 20" wheels, 350 lb rating.
• Simple Step-Thru 20": 500W, 48V 10.4Ah, up to 50 miles, 20" wheels, compact for transport.
• Simple Step-Thru 750W Fat Tire: 750W, 48V 14Ah, up to 60 miles, 26" x 3" tires.

For most riders recovering from surgery, the 500W bikes have plenty of power for neighborhood rides and gentle hills. If you live somewhere hilly, plan to ride trails, or are a heavier rider, the 750W models give you more headroom.

Why Deb's choice made sense

Deb's priorities were leg extension, an upright position, and comfort for every joint, including her wrists. The Relaxed Body E-Bike checks all three while keeping a fairly traditional, easy-to-handle bike feel. It didn't need the extra motor of the 750W bikes for what she wanted to do, and she didn't need the full back support of the Office Chair model to feel comfortable.

Your answer may be different, and that's the point. If you want to compare these designs with three-wheeled options, look at our recumbent electric trikes, which take the forward-pedal, reclined-seat idea onto a three-wheel platform. Riders who want a trike primarily for balance can also browse our easy-to-mount electric trikes.

Deb's story has a simple lesson: the best bike for your body is the one that feels right when you ride it. Spec sheets help narrow the field, but they can't tell you how a pedal stroke feels on a hip that's still healing. Here's how I'd approach the decision if you're in a similar spot.

Start with your care team

If you've had a joint replacement or any recent surgery, ask your surgeon or physical therapist about riding before you buy. Ask when you can start, how long your rides should be at first, and whether there are any motions to avoid. Bring up the specific bike style you're considering. A semi-recumbent position with forward pedals moves your hips differently than a traditional upright bike, and your care team can tell you what makes sense for your recovery.

Get fitted properly

Fit is where comfort is won or lost. Your height, inseam, and arm length all affect how a bike feels, and the same bike can feel great for one rider and awkward for another. Our get fitted page walks you through how we match riders to bikes, and every product page includes our BodyFit tool for a more detailed recommendation.

If you'd rather talk it through, call us. That's literally what I do all day, and I'd much rather spend ten minutes on the phone with you than have you end up on the wrong bike.

Ride before you decide, if you can

Deb's approach was the gold standard: ride all the contenders back to back on the same day. Differences that seem small on paper become obvious when you switch from one bike to the next. If you're near us, you can visit our store and test ride the same bikes Deb did.

If you can't make it in person, our 30-day test ride gives you time to ride the bike at home, on your own routes, and see how your body responds over a few weeks rather than a few minutes.

When you test ride, pay attention to these things

• Mounting and dismounting. Step on and off several times. Notice whether any part of the motion pulls at your hip or knee.
• Feet at a stop. Can you put both feet down comfortably while seated?
• Leg extension. At the bottom of each pedal stroke, is your leg nearly straight without reaching or rocking on the seat?
• Upper body. After a few minutes, check in on your shoulders, wrists, and lower back.
• Throttle and controls. Make sure the throttle, brakes, and shifter feel easy on your hands.

Use the motor to your advantage

One of the best things about an e-bike during recovery is control. Pedal assist and throttle let you decide how much your legs contribute. On days you want to work, use low assist and pedal. On days you're sore or tired, lean on the motor more. You can still get outside and ride without overdoing it, and you can build up gradually as your strength returns, within whatever limits your care team gives you.

Gear that helps

Always wear a helmet, especially while you're getting comfortable on a new bike. You can find options in our sixthreezero helmets collection. A good seat, soft grips, and a basket for carrying things so you don't have to wear a backpack all add up to a more comfortable ride.

If balance is a bigger concern

All four of these bikes are designed for easy, stable riding, but they're still two-wheelers. If balance is a significant concern for you, a three-wheeled option might be a better starting point. Our electric trikes for seniors offer the same comfort-first approach with the stability of three wheels.

The takeaway

Deb walked in with a recovering hip and a clear goal: find a bike her body could enjoy while it got stronger. She rode everything, paid attention to how each bike felt, and chose the Relaxed Body E-Bike for its forward pedals, upright seating, and joint-friendly handlebar position. Whatever your situation, that same process will point you to the right bike. Ride them, listen to your body, and pick the one that makes you want to get back on tomorrow.
