    Scott Sportster p3 2008 with Bafang BBSHD my first Build

    My first experience with e bikes was an Ideal Orama 320ED equiped with Shimano Steps E6000 which I bought early this summer. Don't get me wrong, it's a very nice bike with Auto shifting, you just have to ride it and it does the rest by itself. It has a legal 250W motor and a top speed 25Km/h. So I wanted something more powerful and faster.

    I made a lot of research online and I decided to convert my old trekking bike a Scott Sportster p3 2008 into an e bike.

    I placed my order to fasterbikes.eu and 14 days latter I received my package.

    My Order:

    Bafang BBSHD 1000W E-Bike Mid Drive Upgrade Kit BBS03 - Bottom Bracket Size : 68 mm

    Display : DPC18

    Bafang BBSHD Lekkie Bling Ring 36 42 46 52 teeth Single Narrow Wide chainring - Teeths : 42T

    Bottle Mount Battery 17Ah 52V 14S 5P Jumbo Shark - Cell Type : Samsung 35E, Charger included : 5A with fan + 90/100% switch

    Bafang BBS 2 mm Spacer bottom bracket (2 pieces)

    Bafang BBS 5 mm Spacer bottom bracket (1 piece)

    Bafang BBS E-brake sensor for hydraulic brakes (1 piece)

    Gearsensor Shifting cable adapter

    Bafang BBS Left Thumb Throttle

    Bafang BBS programming cable USB

    2m Spiral Wrapping Band Black, Cable Ø 6–30mm

    Now The build:

    It started well, I removed the crank screws (easy) and then I had to use the crank puller to pull out the cranks (it should have been easy too).

    But the bottom bracket was not a standard one and the crank puller could not do its job. So I had to seek help from a nearby bike shop. They also didn't have a special puller for my bottom bracket, so eventually they had to cut the cranks from the bottom bracket.

      After the first obstacle everything else worked out smoothly. After removing the bottom bracket, the front derailleur the corresponding shifter and the old chain, I cleaned the bottom bracket shell, I fitted the motor into the shell and it was almost a perfect fit.

      I just had to add a 2mm spacer for the bottom bracket and one small stainless steel washer between the motor and the Y shaped fixed holder.

      Then using the special tools I bought, I tightened the steel and the aluminum ring nuts.

        Since I had already found a lot of reports about the fixed holder slipping down with time ( I thing this is a construction weakness of the system), I decided to take measures before having to deal with the problem.

        In a boat shop I found a stainless steel articulated wire tension adjuster used in sailing and using washers I managed to fit it between the upper hole of the motor and the lower water bottle hole at the seat tube. Check the clearance with the Battery in the third picture.

          For the battery holder I used both water bottle holes at the down tube and drilled two more holes where i put 5mm rivet nuts.


          Here is a video showing how to install rivet nuts without any special tools.

          Four screws for the battery holder I think are enough.

          I decided not to use any connectors between the motor and the battery holder, so I soldered the 12 gauge motor wires directly to the Battery holder. If I want to disconnect the battery I just have to remove it from the holder.

            For a Chain Ring I chose the Lekkie Bling Ring HD 42T.

            My cassette is a Shimano 9 speed with Shimano Deore M592 rear derailleur.

            I also put a new 9 speed Shimano chain.

              I placed a new rear shifter wire and the Intelligent shifting sensor just after the swifter at the handle bar to protect it from dirt.

              The E-brake sensor for hydraulic brakes was placed at the rear brake lever (because I always use both brakes) using epoxy glue.

              Both sensors do their job very well!

                The last three pics describe the placement of the DCP-18 display, the display controller and the Left Thumb Throttle at the handle bar and also the final cable management.

                  My first impressions are excellent! Everything works fine, the Bafang BBSHD motor is exceptionally silent and very powerful.

                  The 17Ah 52V 14S 5P Jumbo Shark Lion 910Wh battery lasted for about 60Km with pedaling, after the first 100% charge.

                  The initial Bafang controller programming didn't suit me at all so I still experimenting with this. My current settings are the following:

                    My Bafang BBSHD motor came with an extra 6V 500mA wire coming out from the controller for E-bike Lights.

                    The lights are operated from the display controller or automatically using the light sensor of the DCP-18 display.

                    I tested the wire using a multimeter and it delivers 6.24V, so I purchased an AXA Blueline 50 E-bike Headlight and an AXA Blueline Steady 80mm taillight to complete my project.

                      Hi Stavros. Can you snap a photo of the extra 500mA wire coming out of the controller for the lights. I don't think I have this on my system. Thanks a bunch.

                      When I ordered my system I had the option to order a system with or without this extra cable: https://fasterbikes.eu/en/bafang-bbs...afang-bbs.html. If you can't see it you probably don't have it. The controller has an optional daughter board, a current regulator for that purpose.

                    After a 20km trip yesterday night, I can say that the lights I put on my bike are working just fine!

                      Last week after about 300Km on my Odometer and a flawless ride the night before, I tried to turn on the bike and Error code 30 appeared on the screen (communication fault).

                      I checked every wire and I didn't find any fault.

                      The screen was operating fine, there was correct voltage reading but the battery icon looked empty and nothing else worked.

                      I picked up the phone and called Fasterbikes.eu and they responded immediately. Talked with Patrick who told me to take out the controller and try to disconnect and reconnect the white multiple connector several times but it didn't worked.

                      Talked again with Patrick who thought that must be a controller failure, and he sent me immediately a new replacement controller free of charge.

                      Yesterday, 6 days later, I received the new controller and installed it to the bike.

                          Since I read some reports that when you take the battery out there is still high voltage at the remaining battery connectors which are male, I measured it with my multi-meter and found it about 50V!!!.

                          It is probably from charged capacitors on the controller but I think there is great danger for short circuit, so on my new controller I decided not to solder it directly to the battery base but to use XT90 anti-spark connectors in order to be able to disconnect the controller when I take the battery out.
