Re: Best way to combine two 14 gauge wires into one 75 amp anderson connector?

Solder is not as bad as you think it is. I have never had a soldered connection fail on me in over 20 years.. but i solder with lead.. That's true, and it's consistent with my own experience. However, soldering big fat wires usually results in some amount of wire under the insulation becoming wette...

Re: Coaster Cycles Transit trike?

Has anyone tried to electrify a trike from Coaster Cycles or a similar model? I haven't done a Coaster, but electrifying pedicab trikes from Main Street, Tipke, Cycles Maximus, and Precision is one of the things I do at one of my jobs. We use a Cyclone gearmotor to drive the differential casing. We...

You'll probably need to combine them and fold the end double to get a tight crimp.

Re: VW e-up Li-ion cels

I built a 13S pack with those (which I think came out of a Ford?) and it's the most satisfactory battery I've ever used. It's 26 pounds including enclosure, but worth it. My previous 18650 pack seems like a toy by comparison. I'm only pulling up to 35A, so they'll probably do that job longer than t...

Re: Building a Powerful Ebike

This was going to be my 2nd ebike but I figure I would rather upgrade the battery instead on my first and the brakes as well. Currently its a 1500w voilamart kit from eBay with a 52v 20ah battery. [...] My plan was to increase the battery capacity to around 30-35ah and I wanted to use the same cell...

Re: Building a Powerful Ebike

Whatever you do, get the thickest spokes you can, or use moped wheels. BC eventually at some point you'll rip the spokes out of the rim.. Cheers. The spokes that damage a rim soonest and most often are the thick ones, because they lack elasticity and require higher tension to stay tight. For 6-pass...

Re: Building a Powerful Ebike

Good DH frames are made to ride that speed, down wild mountain trails. Don’t worry, the bike is capable. The rider is the only concern. Those are short events. And racers who reach such speeds don't keep running the same bike season after season. Maybe the bikes can tolerate routine motorcycle-like...

Re: Good for the environment? Maybe not so much

Walking beats a scooter any day from an environmental standpoint. However, by replacing cars - especially for "first mile" or "last mile" applications in conjunction with mass transit - they could have a very positive effect. I hope that's how it's working in some places. In my neighborhood, dockle...

Re: Full Chaincase Solutions - Hebie Chainglider

Hebie Chainglider is a good product. It's quite limited in its chainring tooth count and chainstay length options, though. Once you diverge from the kinds of bike it's intended to fit, it often doesn't. There are different versions of Chainglider available for at least some range of applications. It...

Re: Torque Arm Derailleur Mount

Did anybody try to use the derailleur mount hole for a torque arm? Did it damage the thread of the hole? I wouldn't worry about the thread. It's much, much more likely that trying to react motor torque through the derailleur hanger will bend the hanger or break it off completely. If you're going to...

Moral weakness is contagious. The more people indulge in it, the more acceptable it seems to be.

If we don't snuff out our lineage, our descendants not long from now will wonder how we could possibly have been so stupid, selfish, and short-sighted.

Re: Very high-powered drag braking to control speed while pedaling

I'm not at all clear why you'd want brakes to drag all the time. Is this like some two-wheeled version of those CrossFit morons jogging around with a truck tire dragging behind them? If so, the truck tire is cheaper, easier, and more durable. My experience with a big direct drive hub motor revealed ...

Re: Bike For 3kw Hub Motor

Too much motor, not enough bike. The kinds of bikes you're looking at are complete garbage, likely to self-digest from human power only. Add 4HP and you might well become grated topping for your busted BSO.

My guess is that once you BBS02ify a bike that you like the way it is, you won't like it after that (unless you use the power assist). My BBS02 is enough weirder than my unpowered bikes that it would drive me crazy to ride it without juice. I don't really trust the durability of the clutch or crank ...

If that's a 25km/h motor, it's as good a choice as you'll find for that price. It's still too fast for a trike with only a coaster brake, that's intended for riding at half that speed or less. Be careful, is all. That hub motor wheel looks compatible with a dual pivot caliper brake, as is your fork....
