THE ADULT E-PIT BIKE

The B2 is sized like an 85cc MX or 125cc trail bike, featuring 17/14-inch wheels and a 31.9 inch/810mm seat height (slightly shorter than a Surron LBX). Weight and motor wear are reduced via an unsprung mid-drive motor and lightweight, aluminum swingarm. Bigger, stronger and more powerful than a B1, the B2 is the perfect adult e-moto pit bike platform.

FORM MEETS FUNCTION

The B2's bold moto styling is complemented by its meticulous fit and finish. Notable features include an adjustable 1,000 lb rear shock, durable plastics, true moto brakes, handlebar w/crossbar (not pictured) and 420 chain.

MEGA TORQUE ON TAP

The QS120 V3 special edition motor that powers the new B2 features a 4,900rpm peak, torque bias, and internal gear reduction for increased torque without deviating from a standard rear sprocket. With a recommended constant tune of 125A on 72V, this motor can handle controller peak tunes up to 11kw (riders have even seen 15kw+ bursts).

QSMOTOR is a leader in electric motors due to their quality control, reliability and performance. We tested several motors, and this one came out on top.
