EZ Rider kit for commuter bike
This kit is absolutely brilliant! I did 3,500km on mine in 2 years.
I use my bike to get to the train station, which is 6km away from my home. There is a massive climb on the way back, which is not what I want to deal with after a day at work. I was looking for a compact electric kit to put on my bike, and EZ Rider was ideal. It was shipped quickly, no pre-order wait time like with the alternative one. I really like that the battery is easy to remove and compact enough to throw in a backpack. I just lock the bike, take of the battery and get on the train.
That's commuting, what about longer rides? Weekends - I cycle with my 2yo in a child seat. For its size the battery holds quite a lot of power. I get 20-30km from a full charge depending on the terrain with assist at 2 and 3. I also got a second battery, that I carry in a bag on long rides, which gives me 50-60km range. So, it might be not very obvious, but having a swappable compact battery gives you flexibility. If it was one big battery - it wouldn't be ideal for commuting/shopping - carrying a massive battery in a backpack. I you want to use the bike for long rides - just get a second battery!

I really like the 1,000-watt battery.

I think it would be great if there was a device for even one light with such a good system.

Pleasantly surprised

I had low expectations not for the e-bike kit but for anything that’s road legal in the uk! This kit massively exceeded my expectations. Easy to fit, easy to set up and has changed my 3.5 mile Devon hills commute from an arduous hilly 25mins to an 11 minute leisure ride. I don’t expect it’ll be long before I swap out for a higher wattage kit either 1000w rear wheel or mid drive.

Nice kit

Purchase 2500 W – 3000 W kit 60 V 50 amp controller I received and 72 V kit with a 60 amp controller when I hooked my 60 V battery up battery percentage was not accurate. I went in display to find out I have a 72 V kit I could tell because I received a 60 amp controller with the standard plugs. I contacted Jason. He gave me the code to go into the controller and change it to 60 V. I have 10 amps more power than I purchased. I prefer the other style plugs over the ones I received have not had a chance to take it out. I am waiting on second set of torque arms. That is another story. The rear wheel does 72mph with no load. give four star ready because I received the wrong kit extra 10 A made up for it.
