I settled on a Marin Muirwoods in Tequila Sunrise paint. It has all the required holes for fenders + racks, no suspension, and a cromoly frame. Thanks for your input everyone.

Frame material doesn't matter for hub drives either. Just use properly designed and mounted torque arms or plates. That lives me in a spot where I can't consider a downhill or MTB because they all come with suspension forks and fenders won't fit. No reason you can't put a fender on a suspension for...

Looks like either bike would work and are similarly equipped. Considerations might be battery location, both of which are ample; range of the rear cassette, since you'll be mating it to a single chain ring; seatpost diameter, nice to have a standard 27.2 in case you want to add a suspension post la...

I understand that downhill bikes are a lot more robust. But they don't suit my usage because they don't easily fit full fenders and a rack/paniers. I would be happy enough doing 20-30 km/h on flat ground, I'm not interested into pushing the motor and frame to their limits (not for my first ebike any...

Right, I need 68/73mm square tapered, correct?

How do IGH like the Shimano Nexus fare with the TSDZ2?

I read that only a mountain bike is strong enough for an ebike conversion because of the stronger forces from the motor vs muscle power. However, a moutain bike doesn't fit my requirements: I want full fenders for commuting in the rain, and I want to fit a rear rack with paniers for errands. I still...

Hi Im new to this forum, but I was pointed here from another forum. Ive just converted my Wife's new bike to an ebike using TSDZ2 with custom firmware. I bought a 48V kit from Electrifymybike in the USA. I sourced a 52volt battery from China through DH Gate website. I can say its an easy conversion...

Yes, cheap bikes suck and cheap suspension sucks a lot more (for a skilled rider who rides hard). On the other hand, if it's only for your comfort, cheap suspension will be OK as long as it's not broken. That's what I worry about. Aren't they fragile, especially the cheaper ones? What's their life ...

For your needs, 36v vs 48v almost doesn't matter as you rarely are needing the full power of the motor, except for climbing steep hills. And that's when you'll want 48 volts. And probably half the people who get an ebike don't want a moped, they want bionic legs. But then they ride the thing, and t...

I live in a rather hilly area (Switzerland) and want to build an e-bike that will provide some assist while I pedal: I don't want a moped but rather a "bionic legs" bike. I don't want to go super fast (25-35 km/h on flat is plenty) but I do have pretty steep hills (8-10% grade). I want dis...

Thank you angrybob, that's helpful.

I haven't tried climbing the hill with a bicycle as I sold my previous one and don't have one at the moment. Judging from other cyclists I pass by, they're going 6-7km/h up the hill on the lowest gears. It's very steep. Would a front hub also let me feel like I have "bionic legs" and ampli...

I am used to riding a normal bike and do enjoy pedaling. The reason why I'm looking into an e-bike conversion is because my geeky side thinks it's pretty cool and because the hills are brutal where I live. I would also like to be able to ride 30-50 km easily. Basically, I want a bicycle that helps m...

Do you have a lot of hills to climb? Hub motors also have pedal assist available, and the right motor will climb any hill you want and leave your drivetrain components unstressed by several times the power they were designed to handle. Grin even has a hub motor with an IGH built-in. The motor does ...

New to all this and very excited to convert a regular bicycle. I'm considering using a TSDZ2 because of its pedal assist capabilities and because of the open source replacement firmware. One of the bicycles I'm considering is a belt drive with an internal 8 gear hub. Would the TSDZ2 work well in tha...

I am new to this, and I'm wondering: is the Open Source firmware compatible with the 850c colors display, or is it only with the KT-LCD3? Are there any plans to make the 850c compatible with it? I hope to release in a few days a first version for 850C, here is a picture I took recently from the one...
