StealthDrive is a bolt-on electric drive unit for chain-drive motorcycles. Reverse a 249kg BMW GS with one thumb. Maneuver in tight parking. Roll silently through a paddock. Installs in 30 minutes — no permanent modifications.
If you ride a heavy ADV bike, a track machine, or take your motorcycle off-road — you've been in a situation where your engine is the wrong tool. StealthDrive is the right one.
A BMW R 1250 GS weighs 249kg. Reversing it uphill on leg power is a disaster waiting to happen. StealthDrive gives you a reverse button — one thumb, full control, zero strain.
Navigate paddocks and pit lanes silently on electric power — no exhaust heat in enclosed spaces, no engine noise around crew or spectators. Exactly the right speed, exactly where you want it.
Electric low-speed control through technical terrain — rock gardens, water crossings, tight switchbacks. Back out of a rut without lifting the bike. Silent movement in wildlife areas.
Roll silently out of the garage at 6am without firing the engine. Position precisely in a tight car park. Move it across the driveway without starting up — for the sake of your neighbors and your patience.
Motor size, voltage, and battery configuration are calculated per-bike based on actual weight, sprocket ratio, and wheel geometry.
Compact brushless DC motor mounted at the countershaft. Sized from ~150W (CRF450R) up to ~750W (BMW GS) based on bike weight and physics.
Replaces your existing sprocket cover using the same bolt holes. 15–30 min install with basic hand tools. Fully reversible — remove it anytime.
Most bikes run direct from the 12V system. Small-battery bikes (KTM 390, CRF450R) use an included aux LiPo pack that charges automatically while riding.
Motor housing and connectors are weather-sealed and rated for the same exposure as your chain. Built to live outside, in the rain, on every ride.
Full bidirectional control from the handlebar-mounted controller. Smooth, proportional input — walk the bike anywhere at electric walking pace.
BLDC motors at low speed produce a soft electric hum — not exhaust noise. Perfect for garages, car parks, paddocks, and early morning departures.
