Looking at it from the other end, what ski boots did you wear and would they be ok for pedaling? If you're using AT boots, even lightweight ones like Dynafit, then probably not. I've used cycling for backcountry skiing access (Wasatch) as you're doing, and it can be tricky. If I'm using light...

Those bike builds are good inspiration for me. I need to know more about that middle chrome IGH bike--is that a mid-drive crank? or a mid-drive behind an Andel or Ene Gran Compe crank? I'm a SOMA fan but didn't know about those Condor II bars until I saw them on your build in a pervious post...

sorry to reply to this zombie thread, but Timpo's observation was right on. I've been learning a lot on Grin's site, watching their series of tech "deep dive" videos. So many questions answered that you all kind folks at EBR didn't have to answer for me ;-) I was surprised how committed Grin &...

That's true for a lot of people--it's comfortable and there are still two or three positions on the upper bar. Still well worth it, I think, at least it's clearly worth it to you and would be worth it to me. Back when I was younger (and racing road/track) my bar was 5" below the saddle height...

Those are Origin8 SuperCell, and a lot quieter than the VeeRubber knobbies that came stock. They weigh the same as the VeeRubber 26x4" and pretty close to exactly same width. I was worried they'd be undersized for 26x4" and lower my gearing. There are two SuperCell verions a 30tpi and a 120tpi...

Here is a drop bar conversion I did in April on a new iZip Sumo Bosch. I rode it a couple times with the 70cm wide flat-bar and it's ok but I'm a lot more comfortable on a drop bar, street or dirt. Brakes are TRP Hylex full hydro and they were a straightforward replacement for the stock Tektro...

if someone on a bicycle yells "cheater" at you, yell back "POSER !" trust me, it's like kryptonite. BTW, "pushbike" was the term for bicycle I learned when I lived in Britain. "Pushbike" by then was mainly used by non-cyclists to distinguish a bicycle from a motorbike. If you said, I came here...

Just one perspective but I'm very happy with the four divisions of the Bosch assist. Maybe with a much more powerful motor (mine's a new Activeline with 500wh batt) it would be useful to subdivide more, but as it is, each has a noticeable step up from the last, but not so much increase in power...

It's true that Grin Tech are very helpful with inquiries. I'm an e-bike rookie too, and here's how I learned my way around this GMAC kit: 1. You start with the hub (and choose a winding and that's a question people here will help you with, but for your purposes the standard 10T would probably...

Good information and it's making me realize I should go wide on my upcoming GMAC build. I was leaning toward 42mm tires but the bike will do 50mm tires too. I may try both like you have. It's a steel ~road bike but fairly lightweight (bike is a 22 lb bike before conversion). My first and only...

Looks fun, PedalUma. What tires are you using on that drop-bar Chisel? Looks like 2"/50mm wide knobbies? I'm deciding on tire width for my own lightweight drop-bar GMAC conversion, 42mm or 50mm wide

+1 This is what brought me to the idea of a conversion in the first place. A long-time cyclist, I've always built my bikes from parts, and it's hard for me to want to ride a brand-bike that is not built the way I use it and with the stuff I like. New to e-bikes, I had thought the brand-bike part...

The reason I'm ordering a Satiator is mainly for the ability to select/program an 80-85% charge level (for battery longevity) rather than have to watch the charger when it gets close to 80% and unplug. The second reason may become useful if I decide to get a second battery for an upcoming...

Hmm, good to know. I may find a BB and amend my Grin order.

Thanks for this. I considered motor-drag for the GMAC conversion and went with it anyway. I'm new to e-biking and I've noticed my riding habits using my Bosch mid-drive have evolved in just a few weeks toward using power all the time on the flat and I'm using Eco less and Tour more on the flat...

Thanks for all the information, mclewis and other responders. I studied what I learned on this thread over the week since I posted and I ordered a Grin GMAC kit 10T wind motor (still trying to figure out how wind works), with their 52V 14.5 Ah battery with Panasonic NCR21700A Cells, 40A BMS...

The Grin MAC motor and GMAC motor you mention are the same motor right? HarryS mentioned he gave up on direct drive motors, so I've been looking it up to compare the geared hub motors to the direct-drive. I'm guessing there is a FAQ section or similar here on EBR where I can go learn more...

Very helpful replies so far. This is fun bike stuff to learn. thanks. This conversion would be for road use, but it includes some hill climbing on roads. So something that can do sustained hill climbing without overheating is important, which I've read is an issue for hub-motors. I'm about...

What rear wheel, rear-hub, conversion kits should I be looking at for quality and performance? Lots of eBike conversions (hub or mid-drive) emphasize low cost in order to just get started ebiking and try it out. I've been using a Bosch mid-drive eBike, and now I want to try a rear-wheel...
