Hello, 8)
How Are you making out with your Trike these day???. I have had one for five years and love it, but the motor recently wore out, and I decided to switch to a Mid Drive Motor (I got a 8FUN Bafang). The Trike is still in pieces :'( :'( :'( and has been for six weeks becuase a part on the pedal assembly got stuck (thats where the new Bafang Motor will go), and I had to order a special tool to get it unstuck. Also, I have to remove that heavy and dead motor that it came with. Do you know anything about what I need to put in place of that heavy motor, so that the 2 chains will rotate the wheels???? I havn't taken it off yet, but I imagine there is going to be a gap there. . It's actually hard to find other people that have a Justwin Trike. I guess we are far and few. Looking foarward to hearing from you.

Unless you're good at mechanical stuff ( because you will have to replace the motor with a jackshaft holding the gear cage and the drive sprocket) or want to spend the money at the LBS to have them do it (or suitable mechanical-minded-person) I'd just leave the motor there for the time beings. (makes a great, if heavy, jackshaft).

NO PROBLEMS WITH THE MOTOR after my rebuild back in '12.
I
carefully reassembled the swag clutches and probably modified them a bit, but memory fails me as to what I actually did.
Beleze was ever so helpful during my initial purchase... I can't emphasize this enough.
Running the motor below 30V (7S Lithium Turnigy from HK) probably solved much of my issues with it. I also use a MXUS geared hub motor on the front wheel, which provides a top speed of slightly less than 20mph on 12S of battery.
NOTE: with me riding and all batteries and door the trike weighs over 500 pounds! The tiny geared-hub motor works because it's in a 16" wheel.
Motorizing the front wheel was far better than trying to increase the speed of the rear motor (see: clutch failures) and predates the availability of the mid-drive motors and I'm quite happy with it's performance as I can climb any local grade (including 30%) with no effort on my part
Since I still think the basic trike is a worthwhile investment adding a front motor was a non-issue

As seen by the pics I semi-enclosed the trike, making it more or less rainproof. I did modify the rear suspension to compensate for locally
really strong crosswinds
One thing I've never figured out (because you know... two motor systems) is why the rear motor sometimes fails after hitting a big bump and then refuses to reset unless I do a complete stop.
Obviously I seem to be the only one with this issue.
