this actually looks pretty cool. check it out https://www.addmotor.com/shop/m-360
I ran across this on YouTube, I don't know a lot about E-bikes so thought I'd see if anyone thinks this is possible.
Greg that's an interesting video. 9 kw equals a touch over 12 hp. That 12 hp when driven through a proper gearbox in small motorcycles, less than 250 lbs., often result in top speed of mid 70 mph. I too am an e bike neophyte and can't speak to his e-motive components, but that frame and bicycle running gear are a bad joke. If he intends to continue "lift's of the wheel" and runs 40 mph plus daily he should spend some serious effort in strengthening the frame and upgrading components. I don't dislike his build, but I fear it's fundamentally unsafe at high speeds.
I've run two of my I.C.E. bikes well into the 70's, momentarily, on a couple of short pulls and got away with it. I re-packed the bicycle wheel bearings a few days later and all was good, but there wasn't a lot of lube remaining on the bearings and races either and that taught me a lesson. [My test runs were not on public streets, but were conducted on an airport apron, wearing safety gear. I also had observers & help in attendance during each of these pulls]
The old board track racers did much and fast on early bicycle technology, but compared to our steel, rubber etc. the stuff they used was greatly inferior and many racing injuries & deaths resulted. I'd advise against motorcycle speeds on bicycle tech for the streets. Organized racing on closed tracks deals with a whole different level of bike preparation, advanced skill sets, rules and safety equipment. all directed towards a dedicated purpose, safe racing, and shouldn't be confused with everyday riders and riding.
That's about a 30 mph bike. That's all the frame is good for. Think about the forces involved taking a curve at just 50 mph with good street tires, and a car on both sides of your bike.
If a guy here in Georgia built it he would have said “Hey Y’all watch this” !
Power is easy to make, but if you want motorcycle speeds you need a frame with motorcycle strength, and suspension. Most people understand power, better than chassis dynamics.
I agree, I ride my bikes at 30mph and below, normally at 25 to 26. I've had motorcycles of all types and sizes, now at my age I like to enjoy the sights rather than flash by them. 40+ on a stock bike is not for me.
Why can't more e-motorcycles look like this? It was cobbled together by some ex-employees of Alta, the e-motorcycle company. I'd ride the snot out of it.
Kinda' like you might think Ducati would design a basic naked e-bike...bobbed....I also like!
That's me too. Motorcycles all my life, but my fatty is a 26 mph bike, and I have just as much fun riding it as any other bike I've owned.
I just came in from running errands all morning on my 48 v.1 KW fat tire & I'm really enjoying it and my 36 v. 500 watt mountain bike for daily riding. Since I'm new to e-bikes I'm just enjoying the ride, but it's been all positive with both hub motored bikes.
Because the dirt bike looking frames are cheaper to manufacture. The sheet metal frame and battery box are one thus saving added expense of a custom box. It could be built however the problem lies in design, making a frame with all the features of current ebike frames with curves like a fat bottomed girl.
