What It Does
A thumb-operated lever throttle that mounts to the handlebar with a 22mm clamp and plugs directly into the yellow 3-pin throttle connector on a Bafang 1T4 wiring harness, giving direct motor power independent of pedalling — useful for pulling away from a standstill or, where local regulations allow, riding without pedalling.
Fitment
Fits the BBS01 250W kit, BBS02 750W UART kit and BBSHD 1000W kit alike, connecting via our 1T4 main cable. Works alongside the gear sensor and PAS sensor on the same harness. If you’d prefer a twist-grip action instead, see our twist throttle — note it needs a different connector to plug into a Bafang harness.
Warranty and Returns
Every Thumb Throttle purchased from All4eBikes is covered by a 12-month warranty against manufacturing defects, alongside a 30-day return window.
