Speedbox 3.1 B.Tuning Kit for Specialized eBikes

Bought two speed boxes for my turbo levos and absolutely love them. No more stressing about going fast enough to hit the jumps. I would totally recommend getting one if you are having trouble getting speed past the 20klm limiter.

Great product and easy transaction

Great service on your part and it makes my bike fast and unlimited, which comes in handy on more open trails
