Varstrom TSDZ2B 36V 250W Mid-Drive Motor Kit – Road Legal

The Varstrom TSDZ2B 36V 250W Mid-Drive Motor Kit is a reliable and efficient e-bike conversion system designed to comply with UK and EU EPAC road-legal limits. With a 250W rated output and pedal-assist support up to 25 km/h (15.5 mph), it is fully legal for use on public roads, cycle paths, and pavements when installed and configured correctly.

Based on TongSheng’s proven TSDZ2B mid-drive platform, this kit features an integrated torque sensor that delivers smooth and proportional assistance as you pedal. This provides a natural, bicycle-like riding experience that enhances your effort without overpowering it — ideal for commuting, leisure cycling, and everyday rides.

The mid-drive design applies power through the bike’s gears, improving climbing efficiency and maintaining balanced weight distribution. The compact, quiet motor ensures minimal drag when riding without assistance and long-lasting, reliable performance.

Compatible with most bicycles using a 68–73 mm bottom bracket, the Varstrom TSDZ2B 36V 250W kit is perfect for riders looking to convert a standard bike into a road-legal, torque-sensing pedal-assist electric bike.
