The TSM A5 motor system is a quiet, smooth system that gives a very responsive and proportional boost to your pedal power. It is regen-capable and uses components from Grin Technologies. Up to 1500 watts of electrical power, 28 mph top speed (class 3 + configurable for off-road use), and 50 N-m peak torque.

Check out this video from our friends at Grin Tech for a full overview of this motor and the features it offers!

It features:

  • The TSM A5 motor, a quiet, smooth, and regenerative braking-enabled motor that incorporates a very accurate torque sensor from the German company Innotorq.
  • A hand-built wheel to match your bicycle's specifications.
  • A 52V, 14.5 amp-hour (725 watt-hour) frame mounted battery with Samsung INR21700 50G lithium cells.
  • A Cycle Analyst V3 display that will show your battery charge, motor power output, human power output (calculated via the TSM's torque sensor), speed, and so much more!
  • A throttle (for on-demand power) and brake sensor (for engaging the regenerative braking function of the motor) installed on your handlebars.
  • Stainless steel torque arm, made by Grin Technologies.
  • Customizable control settings (configurable "feel" and response of the system to your preferences!).
  • Non-proprietary, open source components and software so that you can repair, replace, or change out components for the lifespan of the system.
  • 2-year warranty on motor and battery, 3-year warranty on control parts.
  • Professional installation on your bike at our Seattle storefront.
