2026 AnyTerrain Four-Wheel eBike Review: Full Suspension, Hill Climbs and Off-Road Test

Meet the 2026 AnyTerrain: Why a Four-Wheel eBike Makes Sense

I've spent about 20 years in the bike and ebike business, and I've watched a lot of people walk up to a two-wheeler, then a trike, and still hesitate. Not because they don't want to ride. Because somewhere in the back of their mind is the question nobody likes to say out loud: what if I tip over? The AnyTerrain four-wheel ebike is our answer to that question, and the 2026 model year is the best version of it we've built so far.

We added the AnyTerrain to our lineup last year. For 2026 it picks up a few upgrades riders had been asking for, and I want to walk you through all of it: what the machine is, how the unusual front end works, what changed this year, and how it actually performed when I took it out on pavement, over speed bumps, up two steep hills, and across a stretch of rutted dirt I wouldn't want to cross on most bikes. You can see where it sits in the lineup on our four-wheel ebikes page.

An ebike, technically. A quad, obviously.

I call it an ebike out of habit, and in the way it's powered and controlled, that's exactly what it is. You pedal, you get motor assist, you've got a throttle, gears, and brakes on the bars. But one look at it and you can see it's a quadricycle. Four wheels: two 16-inch by 4-inch wheels up front and two 20-inch by 4-inch wheels in the rear. Those are wide tires, and with four of them on the ground, the footprint is completely different from anything on two wheels.

Who is this for? The simplest answer is anyone who wants the ultimate in stability. Some people ride a three-wheeler and love it. Others try one and still don't feel completely settled, especially on uneven ground or in turns. If that's you, if you've ever thought "I just want to know I'm not going to go over," four wheels change the conversation. I'd also put it in front of riders who carry a lot, who want something that rolls across grass or gravel without drama, and anyone looking for an alternative to a trike. If you're still weighing three wheels against four, our electric tricycles collection is a good place to compare.

The tilting front end, explained

The single most interesting thing on this machine is the steering system up front. It's a tilting design. When one front wheel goes up, the other goes down. The two are linked, and they move in opposition to each other.

Why does that matter? Picture rolling over a curb cut, a root, or a pothole with just one front wheel. On a rigid four-wheel frame, that wheel lifts, the frame twists, and sometimes the opposite wheel comes off the ground too. Now you've got less rubber on the road and less control. With the AnyTerrain's tilting front, the wheel that hits the bump rises while its partner drops to meet the ground. At all times, one wheel is always going to be on the ground.

When I'm showing someone the bike in person, I'll rock the front end so they can watch the lean happen. It's a simple movement, but it's the reason the bike feels so composed. You get three things out of it: stability, easier steering, and a surprising amount of agility for a machine with four wheels. It doesn't feel like you're wrestling a cart. It leans and follows your input.

That front end also does double duty as suspension, which I'll get into when we talk about the 2026 upgrades. For now, the takeaway is simple: the design keeps you planted. Every other feature on the bike builds on that foundation.

Where it fits in your life

I think of the AnyTerrain as a utility machine that happens to be a lot of fun. There's cargo space in the front and in the back, so grocery runs and errands are easy. The rear can carry a passenger with the right seat, which I'll cover later. It climbs well thanks to a combination of motor and gearing, and between the front end and the new rear suspension, you don't have to stick to perfect pavement.

For this review I didn't keep it on the easy stuff. I took it through a neighborhood, over speed bumps at a decent clip, up a couple of grades that are genuinely steep, and onto construction-zone dirt that trucks had chewed into ruts. I'll tell you exactly how each of those went, including the parts where a heavier rider like me slows things down. That's the only way a review is useful.

Motor and battery

The AnyTerrain runs a 750-watt rear-mounted motor paired with a 20 amp-hour battery. In real terms, you're looking at speeds up to 20 miles an hour and a range of up to 50 miles, depending on how you use the electric assist. That last part matters. Range is never one fixed number. It moves with rider weight, terrain, how much you pedal, which assist level you sit in, and how often you lean on the throttle. Ride in a low assist level on flat ground and you'll stretch the battery. Run hard up hills all day and you'll use it faster. That's true on every ebike I've ever ridden.

A rear-mounted motor is a good match for a machine like this. The drive pushes the bike from behind rather than pulling it from the front, and on climbs especially, that's what you want.

Pedal assist or throttle: your choice

There are two ways to use the motor. The first is pedal assist. You pedal, and the motor adds power on top of your effort through one of five assist levels. Level one is a gentle nudge. Level five is a lot of help. On the ride you'll see me move from level two up to three on flat pavement and all the way to five for the steep stuff.

The second option is the thumb throttle. Press it and the bike goes, no pedaling required. I use the throttle a lot, especially when starting from a stop or picking my way across rough ground, because it's sometimes easier to control speed precisely with my thumb than with my legs. Some riders pedal almost all the time for the exercise. Others want to cruise. Either works. If a throttle is high on your list, take a look at our electric trikes with throttle control to see how we approach it across the lineup.

Drive and reverse

This is one of those features you don't think about until you need it. The AnyTerrain has a drive and reverse option, so you can go forward or backward. On a two-wheeler you just pick it up and turn it around. On a 120-pound four-wheeler, backing out of a parking spot, a garage, or a tight corner of a trail is a different story. Reverse turns an awkward shuffle into a simple move. We have a whole collection built around this feature, electric trikes with reverse gear, because so many riders tell us how much they rely on it.

Hydraulic disc brakes

Stopping power gets serious attention on a machine this size. The AnyTerrain uses hydraulic disc brakes, and they stop it really easily. Hydraulic systems generally ask less of your hand at the lever than cable brakes do, and the bite stays consistent. If you have any concerns about grip strength, or you just want to feel confident heading down a steep street, that matters. You'll find more models with this setup in our disc brake electric trikes collection.

Seven gears, separate from the electrics

The AnyTerrain comes with seven gears. People sometimes confuse gears with assist levels, so let me separate them clearly. The gears are mechanical, just like the gears on a regular bicycle. They change how hard it is to turn the pedals. The assist levels are electrical. They change how much the motor helps. The two systems work independently, and you use them together.

On the hill climbs later in this article, you'll see exactly why that's useful. I'm in assist level five, the motor's giving me everything it has, and I'm still downshifting to make pedaling easier as the grade steepens. Having gears on a quad like this is really nice, especially if you live somewhere hilly.

The cockpit: display, horn, headlight, and handlebars

Up front you've got a horn, a headlight, and for 2026, a full-color display, which I'll cover in the next section. The handlebars fold down, which helps with storage and transport, and they're fully adjustable up and down with a quick release. You can also tilt them closer to or farther from your body.

That last adjustment is underrated. A small change in reach can turn a ride that feels cramped or stretched into one that feels natural, and you notice it most on longer outings. When your bike arrives, take a few minutes, sit on it, and set the bars where your shoulders and wrists are relaxed. It's time well spent.

Cargo, front and back

You get a cargo basket, and there's carrying space in both the front and the rear. Between the two, there's a lot of room for groceries, a cooler, beach gear, or tools. If hauling is a big part of how you ride, our electric tricycles with a large basket collection shows the range of cargo-friendly options we offer.

Two upgrades define the 2026 AnyTerrain: a new display and full suspension. One is about information. The other is about how the ride feels in your body. Both came straight out of what riders told us they wanted.

The full-color display

We've moved to a full-color display for 2026. It's large and easy to read, mounted right at the front where your eyes naturally go. That sounds like a small thing until you're riding in bright sun and trying to check your assist level or speed at a glance. A clear, bright display means less squinting and less time with your eyes off the path. For many of our riders, readability isn't a luxury. It's what makes them comfortable using every feature the bike has.

Full suspension: the upgrade people asked for

The major upgrade is full suspension, and it's something a lot of people want. On a machine you might ride on dirt paths, grass, gravel, or broken pavement, absorbing impact is the difference between a pleasant ride and one that leaves you sore the next day.

The front: suspension by design

The front end handles suspension in a way that looks nothing like a typical suspension fork. A conventional front suspension has two posts, the ones that look a little like tree trunks, on either side of a single wheel, and they move up and down together.

The AnyTerrain doesn't work that way. The tilting front system I described earlier, where one wheel rises as the other drops, acts as a suspension in and of itself. As you roll over bumps, the front end is constantly adjusting up and down, absorbing the shocks as it goes. Instead of two posts working together on one wheel, you've got each side working independently. Go over bumpy ground and the system responds to what each wheel is actually hitting, and it always keeps one wheel on the ground.

So you get two benefits from one mechanism: vibration dampening and stability. A standard fork smooths the ride but does nothing for your balance. This front end does both at the same time.

The rear: dual springs and a hinged subframe

The rear is where the 2026 change is easiest to see. We added dual suspension under the rear end. If you crouch down and look underneath, you'll find the springs, one on each side. Push down on the back of the bike and you can watch them compress. That compression is what absorbs impact before it travels up through the frame and into you.

There's more to it than the springs. The rear subframe is attached at a hinge point, so when I push down on the back you can see the subframe move as well. There's real flexibility designed into the frame there, and it works with the springs to soak up vibration. The result is a cushier, softer ride that's easier on your body. Instead of a stiff frame passing every jolt directly into your seat, the back end gives a little.

I want to be straightforward about where this matters. On very flat, smooth pavement, the rear suspension isn't going to do a whole lot. It still eases the small vibrations, but you won't feel a dramatic difference. Where you feel it is on speed bumps, broken pavement, curbs, dirt, and anywhere the ground gets choppy. I tested exactly that on the ride, and the difference was obvious.

Why suspension matters more on a seated machine

It's worth thinking about why suspension is a bigger deal here than on many two-wheelers. On a regular bike, you can stand up on the pedals and let your legs and arms act as shock absorbers. On a stable, seated machine like this one, you're sitting down nearly the whole time, which is a big part of the appeal. It also means your seat takes the hits. Good suspension gives you back the comfort you'd otherwise have to create with your own body. If ride comfort is your number-one priority, our most comfortable electric trikes collection is built around the same thinking.

Put the two upgrades together and the 2026 model feels like a more complete machine. The display makes it easier to run, and the suspension makes it easier to ride for longer, on more kinds of ground, without paying for it in your back and hips afterward.

The AnyTerrain was designed as a hauler from the start, and the 2026 frame adds hardware that sets it up to do even more. After the walkaround, I took it out on the street. Here's both.

Rear seat and passenger foot plate

If you weren't aware, the four-wheeler can take a rear seat. You remove the rear basket and put a seat back there in its place. There's a foot plate for your passenger, so they have somewhere solid to rest their feet. You can fit either one adult or a couple of kids. The number to remember is 200 pounds: don't exceed 200 lb on the rear. I have other videos where I walk through attaching the seat and what it looks like carrying a passenger, so check those out if that's part of your plan. You can browse options in our sixthreezero seats collection, and if carrying people is the main reason you're shopping, our rides built for passengers collection is worth a look.

Trailer attachment and canopy plate

Underneath the rear you'll find a new attachment point for a trailer. When I filmed this, the trailer itself was on its way, but the mount is already built into the 2026 frame. Up front, we added a plate for attaching a canopy, which was scheduled to come later in the year. I'm in Southern California, so I know how much a bit of shade helps on a long, sunny ride. Check our sixthreezero canopies collection to see what's available now.

Thinking about total load

One practical point. The bike weighs 120 pounds on its own. Add a rider, a passenger, groceries in the basket, and eventually a trailer, and all of that affects how quickly you accelerate, how fast you climb, and how far the battery takes you. That doesn't mean you shouldn't do it. The AnyTerrain is built to carry. It just means you should set expectations to match. If you're a heavier rider or plan to carry a lot regularly, our high weight capacity collection explains how we think about load across the lineup.

Mounting up and rolling out

With my helmet on, it was time to show you how the AnyTerrain actually performs. I started off on the throttle. You can begin a ride however you like, pedals or throttle, but a little throttle from a standstill just feels nice. It gets the bike moving smoothly before your legs have to do anything.

Right away, real life showed up. A jiu-jitsu class was letting out as we got going, so there was a round of "go ahead," "no, you go ahead" before we could roll. A bit later I had to call out a car up ahead to my camera person. That's everyday riding. You share space with people and cars, and a machine this stable makes it easy to wait at a crawl without wobbling or putting a foot down.

I started in assist level two and bumped it up to level three once we had some open road. On smooth, flat pavement, the ride is quiet and settled. As I said, the rear suspension isn't doing much work here, but it still takes the edge off the vibration you'd otherwise feel through the seat.

Speed bumps at a decent pace

Then we hit some speed bumps, and I took them at a pretty good pace on purpose. This is where the rear suspension earned its place. Without it, on a really stiff frame at that speed, you're going to feel those bumps in your backside. With the rear springs, it was much better. Still a little bounce, I won't pretend otherwise, but it just doesn't hurt the way it would on a rigid frame. I went over a second set and got the same result.

Balance never crossed my mind. With the tilting front end, if one wheel is up high, the other one is down low, and it keeps you balanced through the whole thing.

Hills are where ebike claims get tested, so I picked real ones for this ride. The first I started to call a little hill on camera, then corrected myself. It isn't little. It's pretty steep. I asked Lisa, who was filming, to hang back at the bottom and shoot up the hill so you could see the real angle of it.

Level five and downshifting

I built some momentum at the bottom, then moved up to assist level five, the maximum. I was in seventh gear at that point, the hardest gear to pedal. As the grade took hold, I started shifting down, and each downshift made it easier for me. Near the top I clicked it into third, which made it easier still. Then we were at the top.

That's the gears-plus-assist combination working the way it's supposed to. The motor gives you a strong push, and the gearing lets your legs contribute without grinding. With a single speed, you'd be leaning almost entirely on the motor and fighting the pedals. With seven gears, you can find a pedaling rhythm you can actually sustain.

Rider weight and climbing, straight up

I want to be upfront about something. I'm 230 pounds, and the bike itself weighs 120. That's a lot of person and machine heading up a steep grade. It climbed, and it climbed steadily, but it's not going to rocket up.

If you're lighter than me, you're going to go up that hill a lot faster. The lighter the rider, the faster you climb. That's true on any ebike, not just this one. I'd rather tell you that plainly than have you expect something the physics won't deliver.

The second climb

We had one more short hill before the off-road section, and this one may have been even steeper. I downshifted again before it bit, which is really the key: shift early, while you've still got momentum, rather than after the hill has already slowed you down. Partway up I checked the display and I was going 8 miles an hour. Top speed on flat ground is 20, so for perspective, holding 8 on a grade like that, with my weight aboard, is steady, real progress.

Having the gears is really nice on this quad, especially if you're going to climb hills. I'd go so far as to say that if you live somewhere hilly, the gearing matters as much as the motor.

One more big hill, and an ocean view

After the off-road stretch, which I'll get to next, we came back onto pavement and I shifted into fifth for one more climb. Take a look at the grade in the video. It's a significant incline. Same story as before: steady climbing with the gears and assist working together, and the same weight caveat. The lighter you are, the easier you'll go up. Then we reached the top and pulled over to a view of the ocean, which is about as good a reward as you get for a climb.

What I'd tell you before your first hill

Based on that ride, here's how I'd approach climbing on the AnyTerrain. Build a little speed before the grade starts. Go to a higher assist level early rather than waiting until you're struggling. Downshift ahead of the steep part, one gear at a time, so your pedaling stays smooth. And if you'd rather not pedal hard, remember the throttle is always there. None of this is complicated. It's the same rhythm you'd use on any geared bike, with a motor doing a lot of the heavy lifting.

Into the rough stuff

This is the fun part, and the real test of the full rear suspension working together with the front system. The off-road area we rode is next to an active construction project. Big trucks had been driving all over it, and their tires had chewed the ground into divots, ruts, and creases. Very, very uneven terrain.

There were moments where I said "oh boy" and steered clear of a spot or two, and there was one big crease I went around entirely. That isn't a knock on the bike. It's riding sensibly. Even on a machine this stable, you pick your line.

What the front end did out there

Here's what I noticed again and again. When I went over the bumps, my two front wheels weren't hitting them at the same time. One would drop into a rut while the other was on flatter ground, and the front end kept adjusting for me. Because those wheels operate independently, they create a natural suspension that keeps you balanced, and you can feel it working underneath you.

That's great from a vibration-dampening standpoint, but it matters even more for stability. Bumpy is one thing. Uneven is another. Bumps shake you. Unevenness, where one side of the bike sits higher than the other, is what really creates stability worries. Rolling across those divots, I wasn't worried about stability, and I don't think most riders will ever be on ground much more uneven than what we crossed.

Throttle control on rough ground

I used the throttle heavily on this section. I shifted the pedal assist down even further at one point, but mostly I find it easier to control speed with the throttle when the terrain is unpredictable. I moved back and forth across the track hunting for the smoothest line, picked up the pace when I could, and slowed for the next patch when I had to. Eventually we hit ground I wouldn't call smooth, but way less bumpy, and from there we headed back to pavement for that final climb.

My take on the 2026 AnyTerrain

Here's where I land. The 2026 AnyTerrain four-wheel quadricycle ebike gives you a 750-watt motor, the new rear suspension, the full-color display, and attachment points for a canopy and a trailer, all built around a tilting front end that always keeps a wheel on the ground. It handled pavement, speed bumps, two steep climbs, and some genuinely rough dirt, and I never felt unstable.

It isn't the fastest climber with a 230-pound rider aboard, and you should hear that from me. But for stability, carrying capacity, and comfort, this thing is awesome. If you're looking for an alternative to a trike, it's a great option.
