Just received a Yuba Spicy Curry that my wife will be riding. Great bike but the one thing I don't like is the absence of cutoff brakes especially when down-shifting approaching an intersection, soft pedaling tends to engage the motor. Has anyone have experience with adding cutoff brakes to the...

I've ridden a Haul-a-day with a Bafang motor and have a Big Dummy with a rear geared hub motor (also a Yuba Spicy Curry on the way). The one thing I did not like about the Bafang is that it the assist is on/off. I have a bottom bracket torque sensor on my big dummy and it is a much more natural...

I also have hub dynamos on all my regular bikes. As you note, for most cases it probably doesn't make sense to have one on an e-bike given you have a big battery already there and lights draw a minimal amount. I ended up with one on my cargo bike because (1) I retrofitted a hub motor a year...

Voltron, that's kind of what I'm worried about and/or liability issues if we get involved in a collision of some kind. I've been trying to dig up info on the internet about reprogramming Currie drives but no luck so far

Hi We're looking at getting a Yuba Spicy Curry for my wife here in the US. The slight wrinkle is we are also planning on being in the UK for the next two years and we're planning on shipping the bike across. I was wondering if anyone had any experience reprogramming the Currie Mid-Drive motor...

Check out Henry Kellogg at Liontails cycles. I've had him build me an electric hub motor wheel. Good guy and fair prices and lots of experience with electric hub motor builds.

Thanks for the Kobalt battery idea. While on ebay I also found a bunch of these for sale by various sellers (using Samsung 22p cells): http://www.ebay.com/itm/Replacement-36V-4-4Ah-158W-Battery-For-2-wheels-Self-Balancing-Unicycle-Scooter-/361383652280 Anyone have any experience with the...

Also, is anyone using two battery packs (say 36V 4.5AH) and rotating through them each ride with the ability to connect them in parallel when needed for longer range? I'm considering this also to allow one to travel with them - a 36V 4.5AH battery is right around the 160WH limit for airline travel.

I just came across this post and funnily enough I'm in the midst of a similar build using a Soma Wolverine converted to 26" x 55mm tires with an outrider geared front hub, torque sensor bottom bracket and Alfine 11 belt drive. This is for my 70+ year old dad in Australia but I'm building the...

I come from a similar perspective. I have a surly big dummy, built up my bike, like to pedal and was after an assist for heavy loads and hills and perfectly satisfied with 20mph max. here are my two cents: - i am a big fan of having a torque sensor (this is what is on the bosch system you test...

Can anyone help me identify what this torque sensor (I think) bottom bracket is? http://en.hollandbikeshop.com/bicycle-parts-electric-bicycle/cortina-ecomo-parts/cortina-ecomo-bottom-bracket/cortina-bottom-bracket-120mm-for-ecomo-from-2015/ Zooming in on the picture I couldn't find anything...

This is awesome. I was considering this for my own BD but couldn't wait and ended up going with an eZee hub drive. Seeing these pictures though I might have to move my hub drive over to another bike and get this! I'm very interested to hear how you are going to do the torque sensing. Looking at...

The single chainwheel was a consideration but the thing I most like about the torque sensor living in Seattle is that I don't have to worry about shifting the assist level depending on the grade that I'm riding on and effort I'm exerting. Little/no assist on the flat/downhill if I'm soft...

FWIW, I considered all three of these for a Big Dummy. I ended up not going with the SM as I was interested in the torque sensing right side version (Cycle Stoker) which is only available at the moment for edgerunners and yuba mundos. The LR kit didn't work out timing wise. I didn't like the...

I'm in Seattle also and just bought an eZee rear hub motor and em3ev battery frame pack from Henry at Lion Tails cycles. Good guy, advice and reasonable prices. I also have a steep hill and heavy cargo bike and the e assist has made it a non-issue.
