    New to e-bikes, help with road bike build

    Hi there! I typically ride a motorcycle to work, but want to supplement with my road bike since my commute is only about 10 miles. I have a Fuji Roubaix 2.0 (700c wheels, about 22 lbs., etc.) that I want to add a motor to and be able to ride home without too much assist after a long day at work. Looking at the Bafang Mid drive BBSHD with a 13.5 AH battery and just wondering if that's a good place to start. I've read a lot about mountain bikes and "fat bikes" but haven't yet found a good source for road bike work. I figure with such a lightweight frame range should be great. Any initial help would be much appreciated!

    Cheers,

    GH

    I will be following this thread because I am also interested in e-roadbikes. The only helpful info I can give you is to be sure and run a high voltage in anticipation of a higher max speed for the road bike.

    If I were to make an e-roadbike, I would use a Crystalyte 3580 in the front hub, and a Sabvoton controller at 72V and battery on a sturdy rear rack The max speed would be about 49mph.

      Loosely in the vein (but with a suspension fork and disk brakes) is this video:

        So I'm really close to pulling the trigger on the Bafang BBSHD. The bottom bracket I have is a press-fit bb86 sealed bearing...would the motor work with this? I think I read somewhere that I may need an adapter but I wasn't sure. Thanks!

          Hi gearhead,
          Yes, you will need an adapter. Check out this page for lots of bottom bracket info https://www.empoweredcycles.com/blog...d-drive-motors. If you can't find the proper PF86 to English adapter, you may have to have one custom made by a machinist (I paid $50 for one once). Let me know if you need further help.
          If you haven't gotten the HD kit yet, I might recommend looking at the BBS02 as an alternative. If your riding is all flat land commuting on a lightweight road bike, that might make more sense (it still puts out close to 2hp).

            Matt at Empowered Cycles is an awesome vendor and a great mechanic. I highly recommend him.

              Hi gearhead

              Here are the two most important articles you should read before ordering the BBS02/BBSHD

There are too many variables involved for Luna or the electric-bike forum users to give a definitive answer. The only time


              If you are planning to build a mid-drive BBSxx series bike, then the first piece of information you need is what size and type bottom bracket shell you have.

                From experience a BBSHD and road frame are not a good mix.
                The BBSHD is a great bit of kit but it is heavy. Add the battery and you have a lot of extra weight to carry and stop from a higher speed.
                25mm or 28mm tyres won't be very comfortable even on tarmac. I would look at a frame that will take at least 32mm.
                I would also look at cantilever or V brakes or disc brakes.

                I understand the desire to use a lightweight bike but realistically the e kit is so heavy that other weight isn't much of an issue.
                For a commuter on good tarmac you don't need really fat tyres or full suspension.
