Re: Aluminum vs Steel vs Carbon E-bike Frames

Interesting read http://www.sheldonbrown.com/chicago-schwinns.html The limit for a stock schwinn is approx 8hp, with 4 gussets in the rear and a sleeved seat tube is around 11hp, and with major gusseting and bracing around 15hp. Unfortunately. However, I think that by cutting the rear end off and b...

120/80-14 on a 14x1.85?

Will it fit? There is a 90/100 on it now, it’s a cheap pitbike wheel I got cheap. I want to put the widest and tallest road tire possible.

Re: Aluminum vs Steel vs Carbon E-bike Frames

I like building with steel because it is easy to work with and very, very cheap. $200 welder, $60 for grinder and supplies, $10 map gas and.... $30 worth of local steel for my project. However it is very heavy. I'm looking into cf myself. I'd be looking into aluminum too however, there is nothing ne...

Re: Low cost Down Hill Triple Crown Fork

I have never run a suspension fork I couldn't trust.. So I ended up running a dual crown rigid fork for a long, long time. Worked great, only I lowsided many, many times. But I've never had a front end failure. If I were to buy a fork again, I'd go to treatland.tv in SF and get an EBR hydraulic mope...

Re: Suitable rim width?

You can run pretty much any rim you want. But wider is better for the street. I ran a DM24 in the back for over 10000 miles with tires from 1.95 to 3" wide, riding hard and fast as well. I'd go with a wider rim however, cause tires will wear to a flat and it's better to have a less sharp angle on th...

I'm saving for an ebike... Currently building another gas bike to sell and restoring a vintage schwinn road bike that MAY or may not get a hub motor.

I want to convert this build to electric:

Re: Cheapest e-components for 55mph?

I have a lot to say on the safety of bike frames, brakes, and wheel components. The short version is, respect the power :twisted: Stock steel quality bicycle frames will work fine up to around 4hp with little to no modifications. When my bike was a schwinn, I braced the heck out of it: 212cc Schwinn...

The LED work light from the auto parts store works great. I use the round one with 6 LEDs for $30. Very bright. Main thing to look for in lights is you want flood lights, not spot lights. Those little retro looking ones for $6 a piece on ebay are cheap spotlights which are not so bright, and their m...

Re: E-bike Average speed vs Bike vs Car

Pulling a trailer with a bike kind of sucks. I mean, it doesn't suck THAT bad, and probably not at 20mph for sure, but when you're on it if you need to back up or make a tight u-turn, it becomes kind of a PITA. I built a bike trailer for my bike once, and towed it fully loaded a few times (~250lb) u...

Re: Help sourcing tube clamps

split shaft collars, locking shaft collars, but good luck finding them in 52mm. You could also try some 52mm ID tubing, or 2" ID tubing and open it up a bit, cut it down the length with a grinder cutoff wheel, then weld two nuts on with one drilled out.

You can try treatland.tv , which is a place in San Francisco that sells parts for moped. They will likely have a freewheel for you. If they don't have it listed on their site, send them an email, they usually respond within a day.

2 cross should be fine for you. I just laced a 26" rim with a 105mm pitch circle hub 3 cross. The more crossings the stronger the wheel is to hub forces. I like to always do 3 cross or even 4 cross if there is enough space. Lacing a wheel is easy. If you have a stand its REALLY easy. I used to just ...

Best to go with double butted spokes, 12G would be the thickest to go. You actually want a bit thinner, so 13G/14G butted Sapims if possible on moto rim. Nipple holes on moto rim are quite wide.

Re: Cheapest e-components for 55mph?

My gut reaction is if your gasser is that good, why go electric? Not for legality, that's for sure. Or maybe for legal, but that means limiting power to whatever is legal where you are, which is cheap. Bad ass electric, as you want is never cheap. You will either spend a lot on batteries, or spend ...

Re: Cheapest e-components for 55mph?

If you are willing to use ferro fluid and/or heat sinks, you can run the lighter weight 3k motor, at 5k or more , this achieving 40+ mph pretty easily. I still think that mounting such a setup in a 26" bike rim, is a mistake. You may get the top speed you want on flat roads...but torque will suffer...
