Nothing reminds me more of good bike trips than seeing Tegaderm bandages on the knees and elbows. looks like you're having fun henry

@thekaiser: truckrun or bafang on that frame....the handlebar display is consistent with a truckrun motor. I noticed some obvious rattling with the bafang, figured it was wiring related and moved some stuff around don't notice it anymore maybe I got used to it...maybe I fixed it...not paying attention to be honest. My friends with "pro" ebikes costing twice as much have all had to replace their motors already. The Bafang is going strong by comparison with more riding and more abuse. With careful parts selection my total cost was $6000 Canadian. Many on sale and some used parts hand build asian sourced carbon rims and a Linkglide drivetrain. I still blow through chains however. Performance wise: It blows the doors off everything. uphill/down/flat. I have to turn it off when riding with others on ebikes. I'm a stronger rider but switching bikes I get dropped and find their bikes skittish on the trail by comparison. Mine feels fast and stable, theirs feel fast but not in control It's heavy and that's a GOOD thing. With that much power the weight is irrelevant to pedalling..However it adds stability and smoothness to the ride. The reasoning is the suspension is sprung closer to suspending the chassis rather than the unstable 200lb mass on top of it. The first thing everyone comments on when they ride it is how good my suspension is tuned...it's not my tuning it's the weight keeping the bike from jumping around under you. Bike snobs don't understand this however and still pick it up and scoff at the weight say something about motorcycle then proceed to talk about how great their electric shifter is. Downhill its super stable with cannonball momentum oftentimes I have to scrub speed before a double else I huck to flat. Visiting an enduro park I set a few fastest times of the day on it...without need to pedal significantly just holding momentum. It was way faster than my scott ransom meat bike due to the stability and gravity powering the additional mass. I'd highly recommend building your own vs buying one from industry, I find them overpriced and lacking in durability and performance by comparison with expensive fragile parts that are unnecessary when you have a motor to assist. I break everything and the frame has been beaten badly and is built like a baseball bat. You can PM me for more info All that stated I'm both cycling fit and physically strong and am able to throw around a 70lb bike without much difficulty other peoples mileage may vary.

Ha this is the same as my recent garage build project......Light carbon frame bafang M620 motor Only i spec'd mine better. DT hubs, linkglide drivetrain magura brakes and fox suspension. Frame is from light carbon. Moan hate ebikes and motorcycles all you want. I've pedaled mountain bikes since I was 12. Will state with confidence what I built is absolutely Fn fantastic to ride and the most fun I've ever had on a bike. One ride you'd walk away giggling. Everyone does. Sure it's wrong....but its that cocaine fueled sex kinda wrong

I see this design as a potential fire hazard Riding an e-bike currently and looking how scratched up the bottom of the motor case is I’m very happy there are no batteries there on my bike and that they are higher up the down tube

Yes....My last 9 flat tires and a few for my friends. Even somehow successfully did a sidewall tear 2 days ago. I carry a tube but never seem to need it.

If you want one you can build it. Bafang m620 has more power than is usable in single track. There are a few overseas frame makers making some solid stuff

@hughlunnon: The rider and bike are not a rigid mass and need to be treated separately for suspension performance. t's a 2 spring/damper 3 mass system. Masses that may be accelerating and moving at very different rates sometimes in completely different directions. when tuning my e-bike immediately noticed my fox dps tested on my ebike didn't have enough rebound damping to slow the rebound on the the heavier weight of my e bike and keep it from wanting to eject me in certain situations even on it's highest rebound damping setting. But an e-bike specific fork or shock makes sense to me as t can be stronger sacrifice weight with a No F's given attitude and have a larger range of damping adjustments.

@dkidd: Alot of BS to unpack here....I can see SRAM solving a few self induced problems with this. Point 1 and 2 Folks complain Derailleurs are easy to damage and tough to rebuild. Derailleurs are pretty easy to damage. It's a big complaint. especially when your new electric derailleur costs 500 dollars. Now you can buy a new cage for $175 dollars. Not cheaply.... its more than the price of a high end derailleur from a competitor What I assume is the fuse point (upper link) was not available in their spare parts catalog. Sram solved nothing here but the problems they made by coming up a with 500 derailieur Point 3. b tension and limit screw complexity is not a problem "folks are complaining about" Department store bikes assembled by stoned teenagers may require some solution here. but these are the simplest adjustments in the world. Set once and forget. unless something gets loose broken or bent. Replicable hangars by design are really easy to bend. at which point an electric system will crap itself....hence another self inflicted need for "transmission" bend your hangar the whole system is F'd making your own problem and correcting it is not "innovation" Point 4: SRAM shifting is clunky under load. Yes I have this complaint. Shimano HG+ solved this years ago and cues and link glide solved this at a low price point. Point 4b) Chains and subsequently cassettes wear out too fast.....HERE IS THE PROBLEM FOLKS WANT FIXED!...The crux of this problem is high torque, dirt and a very small amount of lubricant results in significant chain wear. it's not a clunky shift that makes your chain stretch. its the grinding action of an excess of dirt on your chain pins, stretching the chain resulting in premature wear of your rings and cassette. Furthermore ebikes can bend teeth on clunky shifts. Sram made an ultra expensive drivetrain that likely solves bent teeth but not the chain wear. Shimano came to the table with linkglide a steel thicker smooth shifting system that's low cost and will improve cassette wear. Pinion threw away the whole mess and gave us a real transmission, integrating it with a motor that gives you USEFUL FUN (instead of crisper shits) and solved a number of gearbox and e-bike problems in one fell swoop. This is innovation. Point 5: SRAM stuff is still way to expensive. This is not solved. link glide solved this. So linkglide was a bettter solution to things "Folks complained about" While Love or hate ebikes Pinions MGU is the damn future of ebikes and far more deserving of an innovation award.
