    Smallest/lightest mid drive conversion motors?

    You might be better off just looking for a proprietary ebike and let her keep her Salsa as is for when she feels like riding a lighter bike. Yamaha Wabash might be worth a look if you have a local Yamaha dealer with one in stock. There are compromises with DIY mid drives which your wife might...

    I'd be interested in the Pro too but I'm not going to spend over $500 just to find out if it would be adequate for my use or not. I ordered something else instead and when I recieve and install it I'll post up my experience, good or bad, it'll probably take a few weeks.

    Yamaha Exiting US E-Bike Market

    There are quite a few Yamaha ebikes in the couple local dealers when I recently checked their inventory. If they are indeed going to stop selling/supporting the bikes, especially now that a second battery isn't included in the deal, I'm wondering if they will have further steep price cuts in...

    Google translate. It'll even translate text in images which is amazing.

    They list weight as 1.5kg, not sure if that includes the control.

    I wonder how this friction drive unit performs. Couple good reviews on Amazon and one on a Redit forum that I could find. Relatively inexpensive, uses standard 48v battery, retracts from wheel, bidirectional capable, claimed 350w which is more than the Qiroll Pro.

    What I've noticed for mine is that the assist is very noticeable on flats and gentle grades, where it's not needed (where I normally shut off assist on my mid drive bikes) but falls flat on any significant grade where assist is wanted. My experience may be skewed because I typically ride hilly...

    You're welcome, but Blueberry was the source of inspiration - I wouldn't have figured out how/which USB wires were to be used on my own. Interesting choice of adhesive base layer for the sanding belt. I hope it works out for you. Keep us informed either way.

    Nice job with your mounting solution! Just messing around I've put my Qiroll on 4 different bikes in several mounting locations and like best on the seat stays where possible. That way I could easily look down and back at it to see what mode (red or blue) the motor was in as it wasn't always...

    I bought a few of the waterproof momentary lever action micro limit switches and since the braided USB micro cords came as a pack of two I'm going to make another controler using them. Both the push button and lever action switches are much easier to feel and hear when they have been...

    BTW, nice bikes and I'm envious that you had the foresight to buy a Pro instead of Mute, wish I had. Edit: I took a small ride with the DIY actuator and like it. As a bonus the braided cable is somewhat stiff unlike the floppy OEM so routing is neater.

    I just bought what was convenient off of Amazon, two pack of stick on push button momentary micro switches. There are a couple sellers of the same product for $10 or less. Not waterproof, the lever switches that I may or may not try depending on how I like the current setup are even less...

    The DIY switch that I posted above works with same functionality as the stock S2 control. If I like it I'll leave it, if not I might try lever actuation momentary micro switches instead of push buttons or one lever actuated for the "throttle" and a push button for the "mode" selector. Easy and...

    Crater Lake Ride the Rim

    It's a great ride that I try to make every year when life allows, I never get tired of it. It can be done on regular non-closure days also but more fun with the east rim and road to Pinnacles closed to car traffic. This year there were fewer riders which was nice, but even on busier days it is...

    Thank you blueberry. I'm not interested in a brake cut-off myself but I dislike the S2 control so I'm going to see if I can make my own. Ordered a 6ft braided USB micro and a couple momentary push button switches that should arrive sometime today. Plan is to put one button on each handlebar...

    So allow me to show my ignorance. If the Qiroll switch is normally open couldn't you just put a simple in-line on/off switch in series with a normally closed brake cut off switch and avoid having to use a NOT gate (I'm not sure if there are normally closed brake cut off switches but I've read...

    Buck converter worked for me. Enclosed in a handlebar bag it didn't even get warm. Since these motors draw low current there are Buck converters for the load. I did find a 36v output Buck 10a max (not sure what continuous it would support) that might work with a pro but I'm more wanting to...
