Welcome! This is a great group for sharing information. Both bikes look like a good choice for what you want to use it for. Looking over the reviews, it seems like a major difference is that the iZip Dash uses a gearless hub motor and the Evo Cross uses a geared hub motor. The gearless motor...

Generally, a smaller chainring (fewer teeth) will increase the number of pedal strokes required to go a particular distance, meaning, essentially, that it's easier to pedal uphill with a smaller chainring than a larger one. So, if you're mostly interested in hill-climbing, you'd be better off...

Gus, your e-LHT sounds like a great build! Do you have any pics to share? I hope that with a little practice the shifting will become easy. The IGH or NuVinci option is mostly a matter of gear range for me. I got the 44-tooth chainring and if the 11-36 cassette gives me enough low-end...

George, thanks so much for the link. Very interesting. Looks like this shift sensor for the Bafang has a lot of promise, though it appears there may be some bugs to work out first. Definitely worth keeping an eye on. On a related note, I ordered the 500W BBS-02 kit from em3ev, a couple of...

This modular Virtus mid-drive concept by Sunstar looks very intriguing. They're not in the US (yet), but they debuted the system at Eurobike 2014. I think this concept has a lot of potential: mid-drive motor that can be installed or removed for use on different bikes. It also apparently uses...

I'm getting closer to ordering the Bafang BBS-02 kit. I found this good video describing the shifting process with the Bafang. It doesn't seem too difficult.

This Yamaha system looks really cool. Love that it will accommodate double chainrings for hill climbing.

Very cool. Thanks for the YouTube link. It certainly seems like the NuVinci would work if you're careful to disengage the motor with the brake lever before shifting. This seems to be the mode for derailleur shifting with the Bafang, too. I guess it would just require some practice to get...

I'm thinking about a Bafang BBS02 mid-drive kit for my 29er commuter/all arounder (many thanks to Court J. for the helpful info--I definitely thing a mid drive is the way to go). I also had a chance to test ride a Haibike XDuro Trekking earlier today at a dealer, and ... WOW! The Bosch system...

Good info. I appreciate the advice. I've looked into the Bafang, and there's much I like about it, but my main reservations were (1) that it deprives you of a multiple chainring up front, and thus your lowest gear ranges (unless you get a SRAM dual-drive and I don't know about issues shifting...

Hi, I'm new to the forum and I'm considering building a commuter and all-around errand runner with the BionX D-500 kit. I'd be building the kit onto a Surly Ogre 29er with rear rack for hauling stuff and also with a trailer hitch for a small cargo trailer. I live in a hilly area in Southern...
