Re: Critique this performance velomobile idea

If toecutter needs a powered vehicle he can operate over long distances in Texas without having a driver's license, an e-bike appears to be his only option. Anything with a gasoline engine appears to require a license as does the motor assisted scooter. The motor assisted scooter category has a doub...

Re: Zip Tie Failure

I tried a bunch of things for securing my 20lb A123 battery to my rack before I settled on grip tape applied to battery box and rack, and a pair of good old (high quality) bungee cords. They've survived a couple of seasons now, the sun is getting the better of them now and they'll need replacing in...

Re: First DIY Build - input needed (I read the FAQ!)

That and/or figure out how to reconfigure it so that the bike will operate without it. It'll power on and operate the motor without one as long as you short the battery-out and switched-battery-in pins together. Sometimes you also have to short the two data lines together. But it might be stuck in ...

Re: First DIY Build - input needed (I read the FAQ!)

No jokes, it is that the last thing I saw on my handlebars that looked even remotely like that was a bike computer. I haven't bothered to look at what can be done lately. I can't use them around here because they get stolen. The thief doesn't even know what he's got, just cuts the wires and snaps i...

Re: Critique this performance velomobile idea

I'd argue that a flat seat is effectively a "deck." But deck or not, you don't need to have a gas motor for the category. But it does need to be "self-propelled" to meet the definition of "motor assisted scooter". I originally planned to have a thumb throttle limited to 20 mph to conform to the ele...

Re: First DIY Build - input needed (I read the FAQ!)

So that explains the wonderment around here on your range. A lot of us around here don't pedal that much. That Stromer switch is a nice thing. It may have spoiled you a bit. With a kit you are going to have to do the same pedaling as you do now. If you want to have similar control of your watt usag...

Re: Looking for "new" used bike for electric conversion

There is no easy answer. I think buying a good quality used bike is a fine Idea. After all, that's what I did. But if you don't know much about what you are looking at or for, you could find some nasty surprises. You should factor in the cost of doing some maintenance on the bike. Also, keep in mind...

Re: Looking for a chromoly rear rack, any suggestions?

I have the same (or similar) rack that dogman just showed and have reinforced it with similar struts. I further reinforced the seatpost and the rack's cantilever beams with a press fit and glued wooden dowel and plywood rib respectively. The dowel at Amberwolf's suggestion so that any seatpost failu...

Here's where my vehicle wouldn't match the definition:

Re: First DIY Build - input needed (I read the FAQ!)

Sounds like you are an already fit cyclist and that you like riding a bike - electric assist or not. I think you should seriously consider a smaller geared hub motor because that will be a lot easier to pedal without the electric assist. It will feel more like a regular bike. You will lose regen, bu...

Re: Critique this performance velomobile idea

If the resource I found is current, it would qualify as a "motor assisted scooter" even with an electric motor. The statute includes electric motors so long as the don't exceed 40 cubic centimeters of something. The statute is horribly worded in that they don't actually say that the 40 cc spec appli...

Re: cable operated hydraulic brakes

BTW, I thought one of the main advantages of hydraulic brakes was that they reduced slop in the system. Running a cable to a hydraulic caliper would take away that advantage and reduce effectiveness.

Re: cable operated hydraulic brakes

Years ago I spend some time "hotrodding" my Dahon folder. The brakes were a major concern because the main mod was to increase the gearing so I could maintain 20+ mph while commuting. As I recall, the bike had a drum brake on the back and a crappy, no-name, consumer sidepull on the front. Combined w...

Re: Stealth & quick-ish e-bike for short commute, opinions

It may be part of being semi-connected to road bike snobbery in the past, but I also think that putting a kickstand on an e-bike is a great way to communicate "not fast" to others. That motor does blend in. you'd have to look for it. Also, a light motor like that probably doesn't affect how the susp...
