If your e-bike stutters on startup, jerks under load, or shows a hall error code, the hall sensor on the motor is the likely culprit. These tiny magnetic switches tell the controller when to fire each phase. This guide walks through the exact diagnostics, a realistic branch point where your next step changes, and the…
The Bafang M560 is a 750 W nominal mid-drive motor with a peak torque range of 150–160 Nm, delivered through a geared reduction system. It operates on 48 V or 52 V battery platforms and fits frames with a BSA threaded bottom bracket (shell width 68–100 mm). The M560RS variant adds a factory-integrated torque sensor…
If your e-bike’s pedal assist cuts out or never engages, the most likely cause is a misaligned or damaged Pedal Assist Sensor (PAS). On Ideawalk e-bikes and many other hub-drive models, the PAS system uses a magnetic disc on the crank arm and a hall-effect sensor mounted to the bottom bracket. A gap that is…
Most e-bike throttle failures come from a loose or corroded connector at the handlebar or controller. Unplug that connector first—inspect both halves for bent pins, green corrosion, or moisture. Clean with electrical contact cleaner, let dry, and reseat firmly. If that doesn’t restore throttle response, work through the diagnostic flow below in order. Start Here:…
The Bafang M820 delivers 95 Nm of torque at just 2.3 kg with integrated torque sensing and helical-gear quiet operation, making it the lightest mid-drive motor in its torque class. The trade-off: it only works with 48V batteries and tops out at 500W continuous (750W peak), which rules it out for cargo haulers or anyone…
Choose the M600 if you need 120–160 Nm for steep off-road climbs, heavy cargo, or sustained power on technical terrain. Choose the M500 if you value lighter weight, longer range, and quieter operation for commuting, touring, or moderate trails. The wrong pick either adds dead weight you never use or leaves you underpowered on a…
If you are looking past Bafang for a Chinese mid-drive motor, your realistic options are Tongsheng (TSDZ2), Toseven (DM series), and Shengyi (CMT series). Tongsheng gives you the best torque-sensing pedal feel. Toseven runs quieter and handles sustained power better but skips native torque sensing. Shengyi packs the smallest, lightest package and offers an optional…
