The kit is supplied with a 46 tooth single chainwheel, so if your bike has a front derailleur it will not be required.

The brake levers are cable operated, so will not be compatible with hydraulic brakes. We also stock brake sensors for use with hydraulic brakes, which are compatible with Bafang motor kits.

We add additional high quality Mobil Aviation SHC 100 Synthetic Red Lithium Grease to the secondary reduction gears before dispatching motor kits.

Kit is intended for off road use only as it exceeds the legal power limit of 200/250 watts

Easy install, the product was packaged properly and everything works as expected. Happy with my order, thank you Eclipse for all the assistance provided in making sure the kit is compatible with my bike. Review submitted 05/14/2018.

I bought this kit with a 17Ah 48v Battery. Arrived in about 3 days very well packaged. Fitted to my Trek 4500 mountain bike no problem but I had to make a bracket for the down tube as the bottle bosses were in the wrong place. (I have since mounted the battery on the carrier). With a 9 speed (11 - 34) cassette this kit on assist level 1 in 8th (13 tooth) gear wants to do 25Km/hour. On assist level 2 it wants to do 33Km/hour. I sometimes use level 3 for a few minutes (48+Km/hr). From a Full charge down to 20% I got 85Km. This is a great kit and my road cycling has improved as I'm getting more saddle time. My only problem.....I let my wife borrow my bike, now she wants one of hers converted! Review submitted 08/20/2019.
