Bafang mid drive kits are well known for their awesome amounts of torque. Fit a 750W BBS02 motor to your bike and you're in for a treat! Power yourself up to an eye watering 50 km/h, or climb the steepest of hills


The new BBS02-B range of Bafang motors come in 750W. Do you want to go really fast, then this is a great motor for you.

Crank Mounted

The installation of this mid drive electric bike kit, while being a little more complex than a regular hub motor, comes with many more advantages. Engineered by Bafang, a leader in mid drive kits, they will fit any internal bottom bracket.

The Perfect Combination

The latest iteration BBS from Bafang combined with Dillenger's choice of solid battery mounting options and high capacity, high discharge potential Samsung cells make for the ultimate DIY electric bike conversion

Will the NT battery fit my bike?

Sizing up your NT batter to your bike



In general there should be only one measurement that you need to complete; measuring to see if the bottom bracket is within 68mm-73mm. The internal diameter of the bottom bracket needs to be a standard threaded BSA; 33.6 - 33.9mm. Also check your bottom bracket for anything that can be in the way of the motor (such as cable gutters that are sticking out or any abnormalities). If your bottom bracket does not look like a smooth cylinder or you're not sure, please send us some photos so we can have a look. The final thing that you will need to check is if the battery will fit on your bicycle. The mid drive installation can be more time consuming than our hub motor conversion kits. We suggest purchasing our conversion kit toolkit because it contains a commonly used spline bottom bracket tool which and a crank puller (both essential). If the bottom bracket has any small defects like a bur or foreign particle in the way, you may need to use a file to smooth these out. The mid drive kit requires a very good fit and this can make it quite stiff to install, but it will fit!

Excellent kit easy install best purchase i've made in a long time.Review by Jeff Thomas
Functions as Described
Overall Rating
Wow I love the Kit! Easy install and only had to call and ask 1 question. It dealt with the Gear sensor and where to plug it in. I thought it would most likely install to one of the brake sensors since it was the same color. I was correct. Make sure you order the tool kit it had everything you need for the install. The only hardware trip was for zip ties for the cables. Top speed for my 7 speed Townie with no pedaling is 27mph. Plenty fast enough for me. Acceleration is amazing bike balance is great.
Test rode many ebikes first before buying this kit. Most had the high battery over the rear tire"prodecotech" and balance was off, with too much weight in the rear and high.
This kit is low and in the center of the bike.
This out performs, and handles better than the $3000 and higher bikes.
Simply amazing!!!!!!!
Oh by the way, Dillenger beat all the prices out there also, fast ship. I got $1800 in my bike with kit and bike cost. (Posted on 25/11/2015)
