Big Guys & EBikes: 5 Things All Big Guys Should Know Before Buying an Electric Bike

Choosing the right electric bike can be overwhelming—especially for bigger riders who need a bike that feels stable, powerful, and comfortable. I'm Dustin, and after nearly 20 years in the bike and e-bike industry (and being a 230-lb rider myself), I’ve learned exactly what matters most when heavier riders shop for an electric bike.

If you're a big guy looking for your first e-bike, here are five essential things you must know before buying.

There’s a common assumption that the heavier you are, the bigger the motor you need. But that’s not always the case.

Motor Size Rules to Know

• California: Max street-legal motor size is 750W
• Some states: Allow 1,000W
• Off-road/private property: Motors can be much larger, but may not be trail-legal
• 
  

Flat Ground Riders

If your rides are mostly flat, even a 250W motor can surprise you. We’ve had riders over 250–300 lbs try 250W bikes and be shocked at how capable they are.

Hill Riders

If hills are part of your regular route, here’s what to consider:

• 500W: Suitable for heavier riders on hills with some effort.
• (I can climb hills at 230 lbs in PAS 5 without breaking a sweat.)
• 750W: Best choice for big guys who want effortless hill climbing using throttle alone.
• Over 300 lbs?
• Avoid anything under 750W if hills are involved.

Bottom line: Choose your motor based on your terrain and riding expectations—not only your weight.

More weight = more demand on the motor = faster battery consumption.

It’s simple physics.

When I ride with someone who weighs around 140 lbs, their battery lasts noticeably longer, even if we ride the same distance at the same assistance levels.

Battery Recommendations

• Flat terrain, light PAS use:
• 10.4Ah is usually enough for riders up to ~230 lbs
• Hilly terrain or frequent PAS/throttle use:
• Choose 14Ah or 21Ah for bigger riders
• Long-distance rides:
• Go 14Ah minimum regardless of terrain

Remember:

The battery—not the motor—is typically the most expensive part of the bike, so consider your needs carefully.

Comfort is everything—especially if you're a taller or broader rider.

Different e-bikes have different frame geometries:

Compact Bikes (20” Wheels – e.g., Zip 'n' Fold)

Great for portability, but may feel cramped for tall or long-legged riders.

Forward-Pedaling or Stretched Frames (e.g., Relaxed Body)

These are ideal for:

• Riders over 6’0”
• Bigger guys who like more room
• Anyone who wants a natural, comfortable leg extension

Step-Through Frames

Perfect if you want easy mounting and dismounting—especially helpful for heavier riders.

Tip:

Always make sure the frame geometry can adjust to your height and reach. Bigger guys feel the difference immediately.

Heavier riders naturally put more pressure on components. That means:

Tires

More downward force = faster tread wear

More speed = more friction

More miles = shorter lifespan

E-bikes travel faster and farther than regular bikes, so tire wear is normal for all riders—but heavier riders see it sooner.

Brake Pads

Slowing down a 300-lb rider requires more clamping force, so pads will wear faster compared to a 150-lb rider.

What You Should Do

• Check tires and brake pads more often than lighter riders
• Replace pads as soon as you hear rubbing or feel weaker stopping power
• When it’s time for new tires, consider upgrading to higher-end, longer-lasting tires

Think of it just like a car—more miles + more weight = more maintenance.

Not all e-bikes come with gears. Some are single-speed.

But for heavier riders, gears make a huge difference, especially when:

Starting From a Complete Stop

If you try starting in 7th gear at 300 lbs, it will feel like pedaling through cement.

But drop into 1st gear, and even heavy riders can start smoothly.

Climbing Hills

Gears + PAS make hills much easier.

On a 500W or 750W motor, using 1st or 2nd gear keeps pedaling manageable.

Managing Speed & Cadence

• Lower gears = easier pedaling
• Higher gears = more speed & better cadence with higher PAS levels

If you're a big guy, avoid single-speed e-bikes unless your riding is exclusively flat.

Heavier riders can absolutely enjoy e-bikes—you just need the right setup.

Motor size, battery capacity, frame geometry, gears, and component wear all play a role in choosing a bike that feels powerful, comfortable, and safe.
