Provide owners of ebikes to increase their range capacity by installing an extra battery booster system.
Ride the trails longer and forget about range anxiety, carrying a spare battery on your back or riding in small assist modes to get your ride done.
Range anxiety and battery management has always been an issue for me since a serious accident years ago. 2 years of testing and development resulted in trailwatts system.
Giving others the freedom to ride the trails and explore new trail centres or off piste riding on your ebike without worrying about battery anxiety is the purpose of trailwatts.
