Recently purchased the KTM Macina force 293 electric bike with the Bosch performance line CX motor.
I love the bike however when I hit the 25kph mark it's like trying to ride through mud! So I'm thinking about modding the motor. I would prefer to do the internal mod so no extra parts needed etc. Please could someone give me an idea of price and where I can get it done preferably in the Nottingham area.
