There's a separate, simpler mechanism that disengages the pedals if you're coasting - I *think* the purpose of this is so the pedals don't drive the motor if you're pedaling faster than the motor is going, but I'm not entirely sure about that. Now that i know what I'm doing it'll go way fasterĪlso kind of amazed that all of the motor torque gets transferred through that thing with the pawls, especially since it's so buried in the motor - seems like that mechanism could have been external to the motor. I also asked iZip if they sold parts, I'd feel better about it if they could sell me that whole gear assembly and I could just replace it. There is one video of someone disassembling one, although not as far as I went. I was surprised not to find any shop manuals or parts diagrams on the net - does anyone know where I might find one? I wrote to iZip, waiting to hear back, but this really should be a thing they just make available. I also worry the housing that bearing presses into may have already been damaged (there were some metal shards when I took it apart and I think I know where they broke off from) which may have been the source of the problem, so maybe the whole thing will just break again.Īnyways, not really how I wanted to spend 10 (!) hours on a Saturday. I reassembled the whole thing and rode around the block and it works! Although it's noisier than it used to be, I'm not 100% sure I put it back together perfectly (there were a couple washers I should have paid more attention to). But, I put the pawls back (which was tricky) and confirmed that it would now "lock up" in one direction so the gears would turn together. I wish I'd have gone a little slower taking it apart to get a good look at the state of it. So, I took that all apart and you can see a bunch of pawls fell out. If I turned the big gear by hand, the little gear that drives the crank wasn't turning. I confirmed that seemed to be the problem, the motor was running but not providing any power. The part with the pawls only engages in one direction when it's engaged both gears turn together, when it's not they just spin freely. Sorry I don't have a good picture of the thing assembled, but roughly the thing with all the pawls goes around the shaft part, then that whole thing goes inside the bigger gear, then the small gear also gets mounted on the shaft. The bike has throttle, assist, similar balanced weight distribution and is much lighter (50lbs vs. Strong but quiet 500 watt gearless rear hub motor offer. I did some tweeting about the disassembly if you want to follow along but the important part is probably what's in the picture - that transfers power from the motor to the crank. Hi MarcD The Stromer electric bikes feel heavier to me and while its nice to have some cool options in their control interface (and Im sure the ST2 will have even more) I loved the IZIP E3 Dash because it was simple. The 2014 IZIP E3 Dash is a high quality features and well rounded drive system at an excellent price. Hey all, my e3 Dash mysteriously stopped boosting last week, and Saturday I tried to diagnose/repair it (successfully for now).
