Here you can find tuning tools especially for electric bikes driven by Shimano Steps E Bike systems. These tuning devices allow you to remove the 15 mph (25 km/h) speed limit and to drive at least twice as fast with full motor power. The tuning tools can be installed very easily and are simple to use. By the way, it is no problem to undo the tuning again. If you are fed up with your electric bikes speed limitation you should order one of these tuning tools to de-restrict your Shimano electric bike.
The EBikeSpider with an appropriate crank puller can simply replace both Bosch Spider Tools... More info !
