I like my cruiser, it has no stupid mods, I have done 10,000 miles on it and I ride it often and I use both brakes!

R7 race bike developed by Yoshimura, piloted by Ari Henning https://www.youtube.com/watch?v=Tu52zXS_BZs I think this is at a track day, though, not a race, because he has to roll off for the sound booth between 5 and 6. Here is the fastest lap for each rider at the race. The Yoshimura bike is about 3 seconds off the pace, which is pretty interesting because P1 and P2 are on R7s from two different teams. There was a development video posted from Chuckwalla, but I'm having trouble finding it! Anyway, RS660 still leading the championship, but the R7 isn't totally out of it.

Do you know the rules of that class? Those two bikes have pretty different power outputs from stock, is there some kind of power balancing system or are they just free to modify poo poo?

I know, right? I was pretty surprised as well. I'd have to dig, but it doesn't seems like the regulations are publicly posted. Here's what the MotoAmerica site says about the Twins Cup:quote:Putting lighter-weight, twin-cylinder motorcycles in the spotlight, REV’IT! Twins Cup is a rapidly evolving race class that initially enabled regional and club racers from around the country to step up to the MotoAmerica series and compete on a national level. So based on that seems like it's pretty open and just subject to a weight and dyno test? I'm gonna try to find the development video they posted because it really helps to show how much goes into building a competitive race bike. In that video it seemed like everything was subject to review.

Reading that to me implies that they're capped at 100bhp and presumably they'd use a dyno to test compliance. I'd be very interested to see the dyno chart of the two engines compared when they're both making ~100.

And I want to emphasize: the worst most gangster bikes never make it to the internet, they only change hands for cash and they are the two wheeled equivalent of a dirty hypodermic needle.

Honestly that doesn't look bad to me, like yeah it's incredibly basic and the slammed bars are bit much, but overall it's really clean and a lot less hosed up looking than the majority of production electrics.

hah. i know that was probably the only place to put that motor. but the angle of that chain setup means anytime you hit the throttle. a big chunk of the energy goes into compressing those rear springs. probably pogo sticks pretty hard going on/off the gas.

The Home Brew subforum of ElectricMotorcycleForum is full of posters that wish their projects looked that solid. It’s the Wild West out there for EV motorcycle projects. Something about it being more achievable than a car conversion, and less dorky than a homebrew e-bike.

the funny thing about e-bikes vs. motorcycles is at least motorcycle manufacturers have been thinking about working suspensions on two wheel machines for a while ebike manufacturers seem to be catching up to 1970’s moped technology

Though I don't know if this is just a Canada thing or if it's a re-branding of some chinabike that ganked Kawasaki's defunct production line.

For riding on bike paths and in the city, the only suspension you need is fattish tires (like 27.5x3, 700x50, even 26x2.4 ok) on an e-bike. Fight me. I assume most of these home brew e bicycle people are actually trying to make an e-moped, not a e-bicycle. Meaning they are not interested in actually pedaling and they want to go faster than 20 mph while not pedaling. Which is a different goal, with different forces involved and different spec requirements for various safety bits like the brakes. If you wanna talk about e mountain bikes, i can rehash my post about why the yamaha one is terrible and something from giant/specialized/canyon/trek etc will be miles better for actual trail riding and owning.

A proper bicycle company is going to make a better bicycle than a motorcycle company, but ebikes that aren't from Giant/Specialized/etc seem to be a special tier of terrible.

Agreed there. Someone forms a company, go to China, pay bottom dollar, slap their stickers on it and sell it for like 3k. This isn't to say that mainland China can't make great product, but people don't want to pay for it when they can get away with selling garbage that they won't have to do support on instead. Rad Power seem to be a big exception and there are a couple other Taiwanese ebikes that are decent.

I homebrewed my current commuter ebike, mainly because anything store bought here is 250w and more importantly capped at 25 km/h. So I bought a 500W system and slapped on a sound old-ish 29:er I got for a fair price - anything store bought of comparable quality would have been at least twice the cost. I chose the wheel size primarily for the best tire selection (I ride on snow and ice a lot so tires are important) but I admit I like that it looks cool. I mostly ride with an assist limit which is pretty drat close 20 mph but I admit I'll pull out the stops sometimes when nobody's watching and I can go north of 40 km/h. I do pedal all the time, pretty hard when homeward bound since sweating is OK at that point. Pedalling is fun and I sure as poo poo need the exercise. I like and appreciate my squishy fork which lets me go faster and gently caress up more with less drama but it's a fair bit of maintenance and I wouldn't ever call it "necessary". If I were to build or buy or build another bike for the same purpose I'd go more for ruggedness/low maintenance and less for fun/performance. Winters here are really harsh on equipment what with salt water all over the bike paths. Nothing that spins or slides lasts long and anything that can corrode will.

Do you do spiky tires in the winter?

This is what I'm talking about. I'm not referring to suspension, I'm referring to the actual frame design being a collosal piece of poo poo, I've seen bikes that have big wheels but also a folding hinge in the middle for some boomer reason, that kind of thing.
