Yes. Many electric bikes have gears, but some use a single-speed drivetrain. Mechanical gears change how hard it feels to turn the pedals at a given road speed. Pedal-assist levels do something different: they change how much help the motor provides.
That distinction matters when you compare e-bikes. A bike can have five assist levels and only one mechanical gear, or several mechanical gears plus multiple assist levels. Neither number tells the whole story on its own.
Electric Bike Gears, Pedal Assist, and Motor Gears Are Different
The word “gears” can refer to different parts of an electric bike, so start with the rider controls.
- Mechanical gears change the drivetrain ratio between your pedaling and the rear wheel. These are the gears you select with a shifter.
- Pedal-assist levels change the amount of motor support. Raising the assist level does not mechanically shift the bicycle into another gear.
- Internal motor gears may be present inside some geared hub motors. They are part of the motor's construction and are not the bicycle gears a rider shifts.
If an e-bike has no shifter, it may be a single-speed model even though its motor contains internal components commonly described as gears.
The Main Gear Systems Used on Electric Bikes
Single-speed drivetrain
A single-speed e-bike has one mechanical gear ratio. There is no derailleur or gear selector to manage while riding.
This can suit riders who prefer a straightforward setup and whose usual route works well with one pedaling ratio. The tradeoff is less control over cadence when speed or grade changes. Motor assistance can help, but it does not create additional mechanical ratios.
Derailleur gears
A derailleur moves the chain across different cogs. Selecting a larger rear cog generally makes pedaling easier for starts and climbs; selecting a smaller rear cog supports a higher road speed at a comfortable cadence.
Derailleur systems offer a visible range of ratios and are widely serviceable. Their exposed chain, cassette, and derailleur require appropriate cleaning, lubrication, adjustment, and wear checks based on the bike's instructions and riding conditions.
Internal gear hubs and continuously variable hubs
An internal gear hub places the shifting mechanism inside the rear hub. Some provide distinct numbered ratios. A continuously variable hub lets the rider adjust the ratio across a range without moving through fixed gear steps.
Some e-bikes can also change ratios automatically without manual shifting, depending on the drivetrain and its settings.
The exact shifting method varies by system. Some hubs allow ratio changes while stopped, while others require light movement or reduced pedal pressure. Follow the instructions for the hub fitted to the bike rather than assuming every internal system works the same way.
A belt is not a gear system
A belt can transmit power in place of a chain, but the belt itself does not provide different gear ratios. A belt-drive e-bike may be single-speed or paired with an internal hub that provides adjustable gearing.
How Motor Location Changes the Role of Gears
Hub-motor e-bikes
A hub motor drives the wheel independently of the bicycle's chain or belt drivetrain. On a multi-speed hub-motor bike, shifting primarily changes the rider's pedaling effort and cadence; it does not change the hub motor's mechanical drive ratio.
That is also why a hub-motor e-bike can use a single-speed drivetrain. The motor can still assist the wheel while the rider pedals through one fixed bicycle ratio.
Mid-drive e-bikes
A mid-drive motor applies power through the bicycle drivetrain. When the rider selects a different mechanical ratio, that ratio affects both pedaling and how the motor's output reaches the rear wheel.
This makes gear selection and shifting technique especially important on a mid-drive. Changing ratio while the drivetrain is heavily loaded can produce a harsh shift and increase wear. Reduce pedal pressure during a shift and follow the instructions for the fitted drivetrain.
Do You Need Multiple Gears on an Electric Bike?
Not necessarily. The better question is whether one ratio fits the way and places you ride.
Consider a single-speed e-bike when:
- You want no gear selector to manage.
- Your normal route and preferred cadence work well with one ratio.
- You accept less mechanical flexibility as terrain and speed change.
Consider adjustable gearing when:
- Your routes include meaningful changes in grade or speed.
- You want more control over pedaling cadence.
- You regularly start with cargo or prefer an easier pedaling ratio before accelerating.
More gears are not automatically better. Usable ratio range, shifting behavior, motor location, maintenance needs, and the rider's preferences matter more than the number printed in a specification table.
Two Letrigo Examples: KODA and Workhorse
The Letrigo KODA uses a rear hub motor with a single-speed chain drivetrain. The rider does not select mechanical gears. Its assist system and throttle control motor output, while the bicycle drivetrain remains in one ratio.
The Letrigo Workhorse uses a mid-drive motor, a Gates CDX belt, and an Enviolo HD continuously variable hub. The belt transmits power, while the Enviolo hub provides the adjustable ratio.
These two configurations answer the same question in different ways. KODA suits a rider who values a no-shifting setup. Workhorse suits a rider who wants to adjust the pedaling ratio without fixed gear steps.
| Question | KODA | Workhorse |
|---|---|---|
| Does the rider select mechanical gears? | No | Yes, by adjusting the ratio |
| Motor location | Rear hub | Mid-drive |
| Power transmission | Chain | Gates CDX belt |
| Bicycle ratio | Single-speed | Enviolo HD continuously variable hub |
How to Use Gears Without Overcomplicating the Ride
If your e-bike has a shifter, choose a ratio that lets you pedal smoothly without straining or spinning excessively. Move to a harder ratio as speed rises and pedaling becomes too fast.
On a conventional derailleur system, keep the pedals turning with light pressure as you shift. Select an easier gear before stopping or before a climb becomes steep, so you can restart or climb without forcing the drivetrain. Internal hubs and continuously variable systems may use a different shifting method, so use the procedure specified for that drivetrain.
If the bike is single-speed, there is nothing to shift. Use assist according to the bike's instructions and choose a route that suits the bike, your load, and your preferred pedaling effort.
FAQs
Are pedal-assist levels the same as gears?
No. Assist levels change motor support. Mechanical gears change the relationship between pedal movement and wheel movement.
Can an electric bike have no gears?
An electric bike can have a single-speed drivetrain with no rider-selectable gears. It can still provide motor assistance.
Do hub-motor e-bikes need gears?
Not always. A hub motor drives the wheel separately from the bicycle drivetrain, so a hub-motor e-bike may be single-speed or multi-speed. Mechanical gears mainly change the rider's pedaling experience on this type of bike.
Do mid-drive electric bikes use bicycle gears?
Many do. A mid-drive sends motor power through the bicycle drivetrain, so the selected ratio affects how both rider and motor power reach the rear wheel. The exact configuration depends on the model.
Is a belt drive the same as an internal gear hub?
No. A belt transmits power. An internal hub supplies the gear ratios. They can be used together, but they perform different jobs.
Choose the Drivetrain That Fits Your Ride
Electric bikes can be single-speed, use derailleur gears, or use an internal system with fixed or continuously adjustable ratios. Start with your terrain, preferred cadence, cargo use, and willingness to shift. Then check how the motor and drivetrain are combined on the exact model.
If you prefer one bicycle ratio and no shifting, explore KODA. If you want a belt drivetrain with an adjustable, stepless ratio, explore Workhorse.
