The best cadence for an eMTB is not the fastest speed your legs can manage. For most steady climbs, 70–90 revolutions per minute (rpm) is a useful starting range, but roots, rocks, grip and pedal clearance will often force you to slow down. The aim is to keep the motor working smoothly without spinning so quickly that the bike becomes difficult to control.
Cadence is how many complete turns the cranks make in a minute. Choose too hard a gear and the motor may feel laboured while each pedal stroke sends a large force through the chain and rear tyre. One easier gear can make the same climb feel quieter, smoother and more controlled. The 70–90rpm range is a baseline, not another number to chase on the display.
Why eMTB cadence matters more than many riders realise
An eMTB mid-drive combines your effort with the motor’s assistance before sending it through the gears. Your legs may prefer one pedalling speed, while the drive unit has its own effective range.
Shimano’s official eMTB guidance recommends 70–90rpm for its EP8 system, describing that range as the point where the motor gives its most effective output and manages the battery well. That is a sensible general target for sustained climbing on many modern systems, although it should not be treated as a universal specification.
Motor behaviour varies. Some lightweight systems reward a lively spin, while newer full-power motors can produce strong support when cadence falls on a steep step. Software and the bike manufacturer’s tune matter too. Our guide to the best eMTB motors for UK riding explains why drive units with similar headline torque can feel different on the trail.
What is the best cadence for an eMTB in different situations?
| Riding situation | Useful starting point | What to look for |
|---|---|---|
| Smooth fire-road or trail-centre climb | 70–90rpm | Even support, relaxed legs and no labouring motor sound |
| Wet, rooty or loose climb | 60–80rpm | Smooth pressure at the rear tyre without frantic pedal strokes |
| Very steep rock step | Cadence may briefly fall below 60rpm | Controlled power and enough time to place the pedals safely |
| Flat link or gentle gradient | 70–90rpm | Comfortable effort in a lower assistance mode |
| Approaching a technical climb | Shift early, then settle into your range | A clean gear change before the chain is fully loaded |
These figures are deliberately broad. Crank length, fitness, wheel speed and the motor’s response will all change what feels manageable.

Higher cadence can make an eMTB feel smoother
Riders often reach for a higher assistance mode when the bike feels flat, but one easier gear may be the better answer. Raising cadence reduces the force needed from each pedal stroke, so assistance can feel continuous rather than arriving in heavy surges.
That matters on wet UK climbs, where a slow stamp can break the rear tyre loose on a polished root. Quicker, lighter pedal strokes give it a better chance of holding on, although tyre choice and pressure still set the limit. Use our eMTB tyre-pressure guide if the rear repeatedly scrabbles for grip. If your hips bounce or you cannot time the cranks through rocks, move one gear harder; control comes before an rpm figure.
Why low cadence is sometimes exactly what you need
Modern eMTBs cope with short periods of low-cadence climbing. On a steep ledge, you may need to slow the cranks so a pedal clears a rock, or make a partial stroke while repositioning the bike.
Bosch makes this distinction in its 2026 performance guidance, noting that increased torque can help eMTBs at low cadence on very steep, technical climbs. Low-speed torque is a useful tool when the trail prevents a normal rhythm, not a reason to grind a hard gear all ride.
The practical approach is to spin smoothly where the ground allows, then accept a temporary cadence drop when pedal timing and balance matter more. If the motor keeps driving fractionally after you level the cranks, our eMTB motor-overrun explainer shows how to practise with that response safely.
Cadence and battery range
Cadence is only one part of eMTB efficiency. Rider weight, elevation, assistance, tyres, temperature and surface drag can outweigh any benefit from changing gear. Never sacrifice grip or control to protect a few percentage points of battery.
Repeatedly labouring in a hard gear asks the motor for high torque at low speed. Shifting down can move a compatible system closer to its intended operating range and stop you compensating with maximum assistance. Combine sensible gearing with our eMTB range advice, but do not expect one cadence to guarantee a particular mileage.
Cadence and drivetrain wear
The chain feels the combined effect of rider and motor, which is why a poor shift under full assistance can sound brutal. A quicker cadence in an easier gear requires less force from each revolution and can produce a smoother climb with fewer sharp load spikes.
Shift before the gradient bites, keep the pedals turning but briefly ease pressure during the change, then build the effort once the chain settles. Do not wait until the bike is almost stalled and demand several downshifts under maximum motor torque.
Bosch also warns that higher torque and support settings can increase chain and sprocket wear. Our guide to eMTB drivetrain wear covers chain checks, cleaning and replacement in more detail, but riding technique is part of the same picture.
How to find your best eMTB cadence without overthinking it
Find a steady climb with good visibility and ride it in your usual assistance mode. On the next attempt, select one easier gear and pedal smoothly. If the motor feels more settled and the rear tyre holds traction, you were probably grinding before.
If your display shows cadence, try settling near 70–90rpm on the smoother section and then let the figure move naturally as the trail changes. Without a cadence display, count one foot passing the top of the stroke for ten seconds. Twelve turns equals 72rpm; 15 turns equals 90rpm. You only need to do this once or twice to learn what the range feels like.
Keep the same assistance mode while testing gears, otherwise you will not know what caused the change. Once you recognise a smooth rhythm, put your eyes back on the trail and let sound, grip and leg pressure guide you. The best cadence for an eMTB should feel controlled, not like a spin-bike drill transplanted onto a muddy climb.
Best cadence for an eMTB FAQs
Is 70–90rpm the best cadence for every eMTB?
No. It is a useful starting range for steady climbing, and Shimano specifically recommends it for EP8, but motors, riders and trails differ. Technical ground may require a lower cadence for balance and pedal clearance.
Is low cadence bad for an eMTB motor?
Brief low-cadence efforts are normal, particularly on steep technical climbs. The habit to avoid is grinding a hard gear for long periods when an easier gear would let both rider and motor work more smoothly.
Does a higher cadence improve eMTB range?
It can help if it moves the motor into a more effective operating range and stops you using excessive assistance, but cadence is not a guaranteed range hack. Elevation, tyres, surface, temperature and rider input all have a major effect.
Should I change assistance mode or gear first?
If you still have traction and momentum, try an easier gear first. Change support mode when the terrain or fatigue genuinely requires more assistance. Shift before the drivetrain is heavily loaded wherever possible.
The practical answer
For most riders, the best cadence for an eMTB is around 70–90rpm on a smooth climb, adjusted down when grip, balance or pedal timing demands it. Shift early, use lighter pedal pressure through gear changes and listen to what the bike is telling you. A smooth motor, a quiet drivetrain and a hooked-up rear tyre are more useful than hitting a perfect number.
