Mavic electric mountain bike wheels: stiffness, reliability and control under motor torque

Workshop method: start with a safe setting, then adjust in increments of 0.1–0.15 bar.
You are looking for: grip + comfort without blurring when leaning, without heel strike, without rim marks. On e-MTBs, the rear often requires a little more pressure than the front. And above all: respect the maximum/minimum pressures recommended for the tyre and wheel (always apply the stricter limit).

The rear wheel takes more load and more torque: impacts + pinching + stress when accelerating.
To limit this:

• slightly higher rear pressure,
• suitable tyre carcass (reinforced),
• avoid riding with too low pressure on rocky terrain,

insert if you ride hard.

Useful if: rocky terrain, aggressive riding, heavy pressure, or if you want to ride with lower pressure without damaging the rim. The insert protects the rim, reduces pinching and stabilises the tyre under pressure. Disadvantages: longer installation time, slightly heavier, sometimes feels more "cushioned". For demanding e-MTB riding, it is often a good investment.

29: stability, clearance, speed – very effective on e-MTBs.
27.5: more playful, easier to position, sometimes better in very tight spaces.
Mullet (29 front / 27.5 rear): stable front + more agile rear and more margin on steep slopes. Workshop: be careful to maintain consistent tyre/pressure settings, as the rear "suffers" more.

As soon as you notice: less precise engagement, unusual noise, a "scratching" sensation, or after a season of heavy mud/rain. E-MTBs place more strain on the freewheel (torque). Preventive maintenance (gentle cleaning + appropriate lubrication) prevents accelerated wear and tear and surprises.

Symptoms: noise, rough rotation, lateral play when shaking the wheel.
Mistake #1: high-pressure washing (this pushes water/dirt into the seals).

Prefer gentle rinsing, drying, and regular checks if you ride in wet/dusty conditions.

On an e-MTB, a bearing that is developing play is quickly noticeable when leaning into corners.

Check three things:

• Tyre section consistent with internal width,
• Tyre compatible with tubeless,
• Maximum pressure respected.

A tyre that is too wide on a rim that is too narrow = blurred support;

too narrow on a wide rim = "flat" tyre profile, less progressive.

And if you change models, retest the pressure: each carcass reacts differently.

• Tubeless plugs + tool,
• pump (or cartridge),
• inner tube (yes),
• sturdy tyre levers,
• multi-tool, chain tool + quick link, small piece of tape or cable ties.

E-MTB bonus: a derailleur hanger (if your bike uses one) and a small cloth
