Yes, it is something I have been keeping an eye on. So far I've noticed no problems, and that's before I added the extra side braces/ battery/leg protectors. The top tubes are pretty substantial, and the original engine frame was only bolted on, now it's all welded. I've got a good bit of twisty roa...

Hi Ed Getting there slowly, though the weather has been so bad, I'm not really in a hurry. I've just stripped her down to add the battery rollbars and braces, and then the frame is off to the powder coaters. I have had her out for a run up our farm tracks, and she zips up to 50mph with no problem. I...

That's a good idea Beemer, I was going to make side protection bars because, as you can see, the batteries are very vulnerable, so a X config would be fine, and would also give a frame for the side panels. Matt, the BMS is from Elite Power, and seems to work fine. It monitors under and over voltage ...

Hi Beemer I have been thinking about this. I put in an additional brace across the bottom, which the original frame did not have, but I would like to see if I could fit a diagonal cross brace in somewhere. There is a gap between the batteries and motor. I could also brace between motor mount and top...

Well its starting to go together. I've bent and welded up the new front frame, and the batteries are nearly fitted. Then it's on with the wiring. RS do good heatsinks with Tee slots, so I've used one as the base for the controller assembly. The 48 to 12v dropper is mounted there as well. I've got a ...

Steve Thanks for the info. I will probably go with a Kelly controller to start with. As you say, they sell this motor as a package. It looks like a simple unit to get the hang of programming, and if I kill it, it's not too expensive. I've heard it makes a bit of noise at low revs, I assume it's not ...

EBike1.jpg Hello all Here is the start of my latest project. Original bike was a Kawasaki ZR250. Fitting a Mars ME0907 brushless motor, and there is a set of 48v 60AH lifepo4 batteries and BMS coming from Elite Power Solutions, which should be here next week. As soon as the batteries come, I can ge...
