How I Made a Rocket of my RadRover by Installing a 35 Amp Bolton Controller

During the first three seconds of riding my brand new RadRover last year I knew it was underpowered for its class. When I discovered that Bolton Ebikes (now AREA 13 - ELECTRIC BIKES) was offering a specially made upgrade controller, I jumped at the occasion and bought one. I recently finished installing and testing it.

TOOLS REQUIRED
4mm Allen wrench
Philips screwdriver
Flat head screwdriver
Angle Philips screw driver
Side cutter pliers
Combination pliers
A few zip ties

INSTRUCTIONS:
1. Study the video on the RadRover website, then this one again.
2. Carefully read and understand the instructions that came with the controller
3. Remove battery
4. Press and hold mode button to discharge remaining power
5. Flip bike upside down
6. Remove battery cradle
7. Remove the four bolts and the two mounting brackets that hold the stock controller
8. Unplug all four visible connectors
9. Remove rubber grommet with a dull screwdriver
10. Turn handlebars to derailleur side to provide slack in harness cable
11. Push harness cable at the top of the downtube while gently pulling it out at the bottom of the frame
12. Hold the Bolton controller in place tie it temporarily near the opening at the bottom of the frame with a piece of string
13. Feed all the cables through the opening at the bottom of the frame except for the rear light cable, which you will direct upwards to the baggage rack
14. Connect all cable connectors.
15. When it comes to the harness connectors, be VERY careful to align them perfectly. You’ll need good lighting and good eyesight
16. Push the harness connection back into the downtube and pull extra cable out the top
17. Reposition the rubber grommet – if you can!
18. Using one of the mounting brackets and two bolts, secure the controller in place with the tabs at the top of the controller
19. Secure the bottom of the controller to the seat tube by passing a long tie wrap through the bottom holes in the seat tube and around the controller casing
20. Make a seam of silicone seal on each side about 5 inches long
21. Install the display as per instructions in the package.
