Re: Bafang G310 geared hub - 11:1 reduction ratio!!!

We don't have a lot of collective experience with this motor, unfortunately. Hard to say.. Bafang's geared motors are generally good quality. I think that if you are interested in keeping the motor long term, a spare clutch and set of gears is a pretty smart thing to have in your ebike toolkit. Even...

Sounds like a good endorsement. I will probably end up buying them someday, but right now I've already spent too much on bikes, and still have to get the recumbent motorized.
I know the feeling. Now you know why i'm scavenging for coroplast and building fairings this month :lol:

Very sad and a rocky ride, best wishes. The bikes would help keep a focus on the future not the past. Two divorces don't think I can do another one so e-bike's keep me busy. Thanks pal.

Pulled over for being weird.
Typical situation for a velomobile owner, i hear.

I'm quite amazed that you can modify a motorcycle that much and get away with it in the UK. Hats off!

Re: Battery pack revision for Bosch 400

doing so would break the water seals, not something i recommend as the motor has zero protection for water or crap on the inside of the case. You might not even have to drill holes out of the case. There's likely some thickish power wires going to the unit. Those could be reused and sealed with RTV...

and how would you do that? the controller is inside the motor. i got a bunch of detailed photo's of most used mid drives and apart from the bafang they all have the controller on the inside on a extremely custom pcb. only the bafang is universal. If it has 3 phases, there's a way to drive it. Drill...

Option 3 is to bypass the proprietary stuff and free your bike like I mentioned.. IE run a new controller to the motor.

You're right about the magic pie casting heat. It was my weapon of choice for the pike's peak hill climb in 2012 or so. http://neptronix.org/forumpics/pie_pirelli2.jpg I forgot about this factor. Yeah, your vehicle is over 100lbs fully assembled so you could use it. You can, however, get some of the...

Re: Electrom1 Long Wheelbase Recumbent Light Electric Vehicle

If i was you i'd offer a hub with very low rotating losses because you are using a 20 inch or smaller wheel after all. The magic pie for 20" never comes in the right winding and has higher eddy currents than 9C clones because of it's tall stator and additional poles over a 9C type design. The GMAC o...

Re: High performance & durability Cannondale Semi Recumbent

Interesting, but being based on a lowracer is a big nono for visibility.
I have never seen a CLWB ( or something like it ) based velomobile. Taller.

Or something like what craig vetter designed. Tall, but still aerodynamic.

Re: Effect of holes in aluminum rigid fork?

That's just enough power that I would be worried about pretty much any aluminum fork.

There are conversion kits for these weird tapered headsets. I would go that route, plus a steel fork for peace of mind. Front forks are a weak spot on any bike anyway.

I think what you're trying to build is kinda cool. I always liked the idea of a minivelo type bike over a scooter/etc.

Re: Lightweight efficiency oriented BikeE conversion

Man, it's not a strong enough frame to be cutting up and drilling holes in, to be honest. It's a ~33lbs bike, which is pretty light considering how long it is, plus the fact that chromoly ( generally a bit heavier ) is used in the swingarm and headtube. The main tube is super light.. I think another...

Also , I would make a more simple version of the Velotilt , one that has more angular tubes so that instead of an expensive plug for a fiberglass/carbon fiber shell, you could just cut up cloroplast or better yet get some plexiglass and rivet that to the angular frame.

Re: Front suspension forks question

Oh, you can get away with that on something like a big ol' heavy or just long trike..

What i wouldn't do strong front regen on is a run of the mill 2 wheeler bike frame!

Also, that extended length springer fork bent at that insane angle gives me the heebie jeebies.
