How do you know this kit will fit your bike?
Measure the width of your bottom bracket between the pedals to measure your BBS width, as seen below. The inner diameter of the frame bracket should be not less than 33.5mm. If you have a recumbent bike or trike follow the same measuring process as these kits fit those bikes and are very popular for those applications as well.
68mm OR 2" 11/16th looks like this:
73mm OR 2" 7/8th looks like this:
The standard kit will fit 68-73mm wide frames. If you have a wider frame of 100mm or 120mm check out the BBSHD 1000W kit which comes in those sizes.
Approximate range* of each lithium-ion battery:
|Voltage||Amp Hours||Total Watt-Hours||Range (miles)||Range (km)|
|12Ah||576 Wh||25 - 42||42 -
|17.5Ah||840 Wh||34 - 56||55 -
*Range depends on a number of factors such as amount of throttle and pedal assist, type and pressure of tires, type of terrain, rider weight, etc.
1 - Check that there is a 68-73mm (2.6-2.8 inch) gap in your bottom bracket between the pedals.
2 - Check your frame size to ensure the frame-mount battery will fit (L368mm x W90mm x H113mm) (L14.4" x W3.5" x H4.4")
3 - Choose mechanical brakes with sensors (standard) or hydraulic brake sensors.
4- Choose your chain ring: 44T offers the most low-speed acceleration and torque, 52T offers the highest speed. 46T is standard and ideal for a mix of hills and flat terrain and everyday riding. Please leave us a note when placing your order for the type of chain ring you'd like!

Great kit ,install was straight forward. Tim at Cyclecharged made it all work. My only complaint was the amount of cabling. A shorter main harness (90cms) down to 30cms would have made a neater finish. Fun to ride though.
Yes are still waiting for the battery for the last command we made.
We bought Two other kit and we love it but the dysplay of the first kit is already broken we had to buy another one.
I ordered and built a bike with this kit 3 months ago and have been loving it ever since. It was easy to install, the videos were very helpful!
I ride every day and it has made it so much less daunting to transition to choosing the bike over the car. There's already almost 400 miles on the build and I have had no problems. Mark walked me through ordering and helped with questions and mix-ups I had while ordering. Great customer service!
Purchased a mid drive kit to install on my wife's step through Raleigh. Delivery time was better than promised. Cyclecharged response to questions was very timely. Viewed several videos on installation to cover various issues. Installation went well, pretty much plug and play. Only issue I had with the kit was the included wrench for the outer ring was slightly small. Was able to tighten it otherwise.
Due to the weather in Ohio, it's only been ridden for a few miles on the initial test ride, but so far so good. Looking forward to giving it more of a workout soon.
Would definitely do business with cyclecharged again.
I had been looking at purchasing a Bafang E-Bike kit for over a year. I had a hard time getting myself to pull the trigger. After much delay, I looked at cyclecharged.com. Still concerned, I started asking questions with the online chat support with this site. They patiently answered all technical questions and concerns about installation, compatibility, performance, etc. Finally I ordered 2 kits for my wife and I. The unit came about a week ahead of what I was told when ordering. I watched at least 10 videos on youtube.com showing various issues that I may run in to during the install. Once I started the project, I had both units installed in about 4 hours. The first one took about 3 hours because I could not get my old pedals off my bike. The 2nd unit was installed in about an hour as I avoided mistakes on the first build. As I finished the 2nd unit, I noticed that the battery mount was cracked. I took pictures and sent in to cyclecharged.com support. They sent me a new mount shortly after. I am very happy with these units and I am very happy with the support and follow up I experienced with cyclecharged.com. On a scale from 1 to 5, they are a 6!!
