Firmware regen weak, medium, or strong changes how often friction pads touch the rotor. Use this guide to calculate brake pad wear from regen settings—translate your regen share into km per pad set before you blame hills or pad quality alone.
Benefits
- Regen factor = 1 + (100 − regen %) ÷ 200—explicit link from settings to wear rate.
- Compare km per pad set at low vs high regen with the same weekly km and hill share.
- Weeks per pad set updates when you change only regen—isolate motor braking from route mix.
How it works
- Fix weekly km and hilly route %—change only regen braking share between runs.
- Note regen factor and km per pad set at each regen level (0 %, 20 %, 50 %, 100 %).
- Pick the regen setting that balances pad life with stopping feel on your commute.
FAQ
How do I calculate brake pad wear from regen settings?
Enter regen braking share (%) in the tool. Regen factor = 1 + (100 − regen%) ÷ 200. Km per pad set = 1200 ÷ (regen factor × hill factor). Higher regen lowers the regen factor and extends pad life on routes where motor braking actually replaces friction stops.
Example: 20 % vs 50 % regen at 30 % hills?
At 50 km/wk and 30 % hilly (hill factor 1.3): 20 % regen → factor 1.4, ~659 km; 50 % regen → factor 1.25, ~738 km. Doubling effective regen share adds roughly 80 km per pad set in this scenario—hills still cap the gain.
Does max regen eliminate pad wear?
No—at 100 % regen share the regen factor is 1.0× baseline, but hill factor still applies. Steep descents and emergency stops use friction pads regardless of firmware regen level. Wet or low-SOC routes may fall back to friction more often than the regen % suggests.
Where do I find my regen share?
Estimate from app settings (weak/medium/strong) and riding style—count how many stops feel like motor drag vs lever pull on a typical flat commute. Enter that percentage; refine after one week of mindful braking.
Technical specifications
- Regen factor = 1 + (100 − regen %) ÷ 200.
- 0 % regen → factor 1.5; 50 % → 1.25; 100 % → 1.0.
- Km per pad set = 1200 ÷ (regen factor × hill factor).
- 50 km/wk, 30 % hills: 20 % regen ~659 km; 50 % regen ~738 km.

Regen share is a wear dial
To calculate brake pad wear from regen settings, map firmware regen level to a braking share percentage. The tool's regen factor rewards higher motor braking on flats—each step toward strong regen shrinks friction duty and pushes km per pad set upward until hills dominate the result.
Compare settings before upgrading pads
Run the calculator twice at the same weekly km: once at your old weak regen estimate, once at medium or strong. The km delta shows whether tuning regen buys more life than switching pad compounds—often meaningful on flat 50 km/week commutes with modest hill share.
Regen does not replace descent brakes
Even at 100 % regen share on paper, hilly route percentage still multiplies wear through the hill factor. Pair regen comparisons with hill-climb load checks on the same commute—controllers that regen hard on flats may still fade on long downgrades where friction pads do the work.
