The Bafang mid drive from Dillenger Electric Bikes has arrived for testing and review!
Bafang offers one of the few mid drive electric bike kits that can be installed on a traditional bicycle.
A lot of the mid drive systems (Bosch, etc.) only come on complete bikes with a specialty frame.
This system from Dillenger is the 750 watt version of the Bafang mid drive. Dillenger also offers Bafang mid drive systems in 250w, 350w, and 500w sizes.
750 watts is the highest power allowed by US law to still be considered a “bicycle”.
Since this system is being used on the Xtracycle Edgerunner cargo bike, 750 watts seemed like a good idea to haul heavy loads!
This kit is priced at $1,299 USD at the time of this review.
In this first part of the review there are a BUNCH of detailed pictures and specifications to get you familiar with the Dillenger Bafang mid drive kit.
Part 2 of the kit review will give you info on the ride characteristics, results from the range test, pros, cons, and overall thoughts on this e-bike kit.
Alright, let’s get into the details!
Pictures of the Dillenger Bafang Mid Drive Kit
Here is a look at the major components that are included with the kit. The motor, cranks, chainring and chainring guard, LCD display, battery (and charger), and brake levers. There is also a package of small parts not shown.
Now let’s take a look at the installation of the system on the Xtracycle Edgerunner. The old cranks and bottom bracket were removed from the Edgerunner.
Here’s a look at the left side of the Bafang mid drive motor. 8FUN is the shortened Bafang name. To the right of the motor is the gearbox and bottom bracket spindle.
This is a look at the right side of the motor and gearbox.
Installation of the 46 tooth chainring with the included screws.
Installation of the motor spindle assembly into the bottom bracket of the frame.
The motor spindle assembly installed in the frame.
A fixing plate has “teeth” that lock into the bottom bracket of the frame. The fixing plate fits over the spindle assembly and……
Is then attached to the motor with the included screws.
After the fixing plate is attached then the first locking is attached and tightened.
And then a second lockring is attached and….
Tightened to secure the motor to the frame.
Then the left crank arm is installed on the spindle. The inside of the crank near the pedal attachment indicates a left or right crank arm.
Lining up the crank with the spindle.
The crank is attached and the crank screw tightened.
Then the left pedal is attached and tightened.
Next, the chainring guard is attached to the chainring with the provided screws. Then the right crank arm and pedal are installed just like the left side.
A wheel speed sensor is installed at the rear wheel. The magnet attaches to the wheel spokes and the sensor is attached to the frame. I used a Bafang speed sensor extension cable because the rear wheel on the Xtracycle Edgerunner cargo bike is further back than most bicycles.
This is the battery mount that is normally attached to the water bottle mounts on the downtube of most bikes.
The Xtracycle Edgerunner has an area in the frame between the seat tube and the rear wheel where the battery mount can be installed to keep the battery out of the way.
In this view, the Dillenger 48V 8ah lithium battery has been installed on the battery mount. The included key locks/unlocks the battery from the bike. Above the key is the on/off button for the battery. The battery must be turned on before the Bafang mid drive can be turned on via the control pad at the handlebar. More on this in a bit.
On the right side of the battery is the charging port. The battery charger is about the size of a laptop charger and can be plugged into any normal wall outlet. It takes about 4 hours to fully charge the 48V 8ah lithium battery.
The battery can be easily unlocked and removed from the frame for charging inside.
Bonus! A USB charging port is located on the right side of the battery for charging smartphones, tablets, MP3 players, etc. while out and about.
The Xtracycle Edgerunner has side bags or the flat cargo platform for placing a smartphone while charging.
The Dillenger Bafang display is large and easy to read. It is positioned front and center on the handlebars. The LCD display provides info on: speed, odometer, trip distance, battery level, pedal assist level, and time. It also has a backlight for visibility while riding at night.
The display is attached with clamps and 4 screws.
The simple control pad has the on/off button and the pedal assist adjustment buttons (+ -). Using the combination of these buttons allows you to set the custom features of the Bafang system; like up to 9 levels of pedals assist! To the right of the control pad is the thumb throttle that adds boost to the pedal assist or you can use it as a pure throttle without the need to pedal.
Brake levers with “kill switches” are included with the Dillenger Bafang mid drive system but I did not use them because the Xtracycle Edgeunner that I am testing the system with has hydraulic disc brakes and these levers are not compatible. For cable actuated brakes, these levers will send a signal to the system to stop the motor assist when the brake lever is engaged. It is a nice safety feature to have.
Once all of the components were installed the connection of the wiring was easy because the inside of the connectors were color coded to match and there were alignment arrows to help with the correct connector orientation.
Ready to roll! The Dillenger Bafang mid drive adds a charge to the Xtracycle Edgerunner for commuting and hauling heavy loads. It makes for a good car alternative or…..replacement?! Stay tuned for part 2 of the review with more info on the ride characteristics and range test results.

Review Note: Each company pays a fee for a review on Electric Bike Report because of the considerable amount of time that it takes to provide an in-depth review of each eBike. A lot of time is spent on the full range test with distance & elevation profile, the wide variety of detailed pictures, in-depth video, and the write up with the specifications, ride characteristics, pros, cons, and overall thoughts. The reviews on Electric Bike Report are focused on providing you with a detailed “virtual” look at each eBike to help you determine if it is the eBike for you or not.
