Bymoss Bike is currently the only company offering a road-legal electric retrofit system for BMW R Series motorcycles, from the R45 to the R80, while retaining the original gearbox. This unique solution is officially homologated for road use in France, Switzerland, and Monaco, marking a first in France and paving the way for future European-wide approval. The project is the result of close collaboration with Luuc Muis – LM Creations.
Bymoss Bike is also the only retrofit specialist in France and Europe to preserve the original BMW gearbox, a defining element of the Airhead riding experience.
A respectful and authentic approach
Bymoss Bike’s philosophy is to replace the internal combustion engine with an electric motor without compromising the soul of the motorcycle. Each conversion preserves:
The original BMW gearbox, a key part of the riding feel
The historic design and proportions of the BMW R Series
A premium, handcrafted finish, executed with meticulous attention to detail
The result is a motorcycle that feels authentic, balanced, and unmistakably BMW, now reimagined for a cleaner future.
Current offers
Bymoss Bike currently offers two distinct solutions:
Turnkey electric motorcycle
Available in Scrambler or Café Racer configuration. This offer includes sourcing the donor bike, full restoration, and electric conversion.
Starting from €19,990 incl. VAT
‘Simple Retrofit’ conversion
Designed for customers who already own a BMW R Series motorcycle. This includes removal of the thermal engine, installation of the electric system, and full homologation.
Starting from €9,990 incl. VAT
This is a particularly favorable period, as public incentives may still apply in France, up to €1,500 for private individuals and €3,000 for professionals, depending on region.
In addition, any order placed before January 31, 2026 includes a ROEG open-face helmet offered with the motorcycle (brand reference: roegmoto.com).
