    Does anyone have experience installing a mid-drive eBike kit on a handcycle?

    I'd like to install a mid-drive eBike kit (e.g. eRad) on my Top End CC handcycle, and would be very interested in learning about any best practices, advice, or ideas.

    I have a friend who installed one on his RX, and he loves it. I've been asking him questions about the project to learn from his experience.

    Has anyone tried this? Thanks!

    Not sure what you mean by mid-drive. I use one of Mark Brertons Roadrace Powerpods. He used the rear half of a bike, designed a hitch with latchesa nd away we go. I've got up to 35mph without pedaling with it. It coud have gone faster but that was fast enough.

    The lithium 48vt20ah battery made it like a rocketship taking off.

      Hi Patrick. The mid-drive motor is essentially a crank assembly attached to a motor. Bafang and eRad are two brands (same company, two brands) of kits you can use to retrofit a normal bike to ebike. The units come with a control pad and display, and they can provide a partial assist similar to a Bionix hub motor.

        lasher had been doing it, never saw on rx before post up pics of your buddies if u can. we have always used bionx with great success on our Quad Elite builds but they are in receivership and we sold through the 30 we had at the shop.....

          Thanks John. I’ll check into this and post some pictures. I found another person who is in the process of installing one on a Top End Force 3, so hopefully some additional input once he’s finished with the project.

            Hi everyone,

            Sorry for the delay on this. Here's a quick update. First, here are some photos of friends' projects. One installed a mid-drive motor on a Force3, the other installed a mid-drive motor on an RX. The photos give you an idea of how the motor is installed. Second, I'm having a local bike shop (also a bike maker and fabricator) install the motor on a Top End CC for me (purchased it used a couple of years ago) because I just don't have the time right now. So, stay tuned and hopefully I'll have more to share. Some things that I've learned along the way:
            - Motor and material were sourced from Lectric Cycles (www.lectriccycles.com). The motors are Bafang, but according to the bike shop this company has worked out some of the reliability/consistency issues with the kit.
            - I ordered a 750w motor b/c I live in an area of California with hills, so the motor will likely get a workout.
            - Since I'm not getting a throttle (the system will be assist-only), I'm skipping the brake sensor but will likely still get the shift sensor

            I'm really looking forward to getting the motor installed.

              eassist is the future imo. ppl are realizing u actually get a better more consistant workout with assist. i have a 500w bionx on my QUAD ELITE and hybrid stricker, my HR gets up and stays up consistently and way longer. win win
              are you going pedalic or torque sensing

                Totally agree. For me, the biggest advantage is that it will provide me with far greater options for cycling - where I can go, who I can cycle with, how long I can cycle. And I agree with your point around consistency and fitness level. I'll document what I can to pass along info for others. I believe the system will be pedalic, but not quite sure of the difference. Can you clarify?

                  pedalic- normally at cranks, senses and kicks assist in as cranks rotate
                  torque- senses torque/pressure to kick in assist

                    Awesome thread, I have an awesome Lasher that has been sitting. This sounds like the spring project I’ve been looking for. Any thoughts as to + - of brands? Bosch, Yamaha, Bafang?
                    Thanks Mark

                      I looked around and from what I've seen you want to purchase a 'kit'. The kit from Lectric Cycles (www.lectriccycles.com) uses the Bafang motor and components, but according to the LBS that I'm working with they've sorted through all the components to weed out the more unreliable components. I decided on the 750w motor b/c I thought the 350w might be a bit underpowered given the hills around my area. I really wished that Lectric cycles offered a 500w motor. Their lineup jumps from 350w motor to a 750w motor, so I ended up going with the latter. I expect to hit some issues along the way, and will post anything I find.

                        I haven't had a power assisted handcycle, but I agree with y'all that it's probably a much better workout. When I gave handcycling a shot (not currently feasible where I live), I remember many places I wanted to go had big hills, which I would hit, and then in the bottom gear I would be cranking at 20 or 30 revolutions per minute, creeping along for several minutes. Impossible to keep up the heartrate when struggling to climb a hill like that. If I was able to power over the steep hill and continue the ride on more reasonable terrain I wouldn't lose my cadence like that... plus it would be way more fun

                          exactly. we were all boneheads for many years regarding assist and how it would feel like slacking, even though many old timers told me how much better of a workout it is. they were soooooo right, my workouts, consistent higher heart rate, cadence, speed and overall enjoyment level is much better with assist. not to mention all this equates to more calories burned per session.

                            Mark Brereton Roadrace Powerpod for sale BO

                            I have the Mark Brertons Roadrace Powerpods motor like the second post up from here. is available for sale if anyone is interested. I sold my Force G handcycle so I don't need it anymore.
                            The main advantage of having this instead of the mid-motor or the bionic emotor is that you can still use your handcycle without the motor, like if you're racing or something

                              I agree Cybermex, it takes less than a minute to unhook the PowerPod and be completely manual. Nothing like going 30t mph and not even pedaling. It's been perfect for these worn out shoulders.
