Took my time to carefully install the kit by following pdf instructions, but actually it was dead simple to fit (even lowering motor) Used blobs of hot glue to fix electromagnet securely to motor (as shown in Aussie YouTube vid). Job done! First test-ride gave me a biiig grin. The bike now rides more like a regular bike as you don’t hit the ridiculous ‘treacle wall’ after passing 15.5mph. Fastest I’ve got so far is 24.5mph on the flat in eMTB mode. My happy place is around 17/18mph in eco mode. Purion display stats are out the window, so use Strava app or similar to clock speed, distance etc. I’m weary to not exceed 25mph (as advised) and occasionally check sensor/magnet distance stays within required space/mm limit to avoid error messages. Switch off flow app software updates to avoid error messages & consider the app redundant before you start. It’s worth it! Jim, Scarborough.

Completely changes the riding experience!!

I love the speedi and have used it on multiple wheel sets and bikes. Easy to install and don't have to worry about it interfering with the motor.
