Re: OP Lek-Trek (Light Weight MTB Turned Hybrid)

Ah, i saw that one, but it is far too small for me. Honestly, i need a 21" frame. That looks like a 16".. hehe. Thanks though. That thing looks totally cherry... garage queen if there was ever one O_O. Wow.

If you've got the kit setup i wouldn't mind ridin' that thing though!!! that's for damn sure.

Re: OP Lek-Trek (Light Weight MTB Turned Hybrid)

Looking to get a trek 830 or 930 actually, sold my trek 4000 just recently because it was too small, having trouble finding another too!
Be on the lookout for a clone of this bike roaming the streets of Portland. ( except i will probably be using a cell_man motor )

Re: Farfles Iron Horse build

So hey, are you building an eBike on an 'iron horse' bike? Just thought i'd warn you that Iron Horse went bankrupt over perpetual welding defects in their frames. I found this out when i was comparing trek, giant, iron horse, gary fisher etc frames. If it's an Iron Horse, you may want to look into w...

Re: Kepler Friction Drive System (sale thread)

Is it correct that the first batch will NOT have the interface? IMO, that takes the bargain right out of the equation, while still being somewhat reasonable, but now we are talking $500-600 without the interface for a complete kit. How much extra will the interface be? That was one of the selling p...

Re: Specific Climate Impact of Passenger Transport

Well, to be fair, a typical bicycle only has an advantage at low speeds. You see the big motor guys on here, saying they pull 5000watts+ at > 50 mph. That's basically the same as an economy car. If all of us could store 20kw in a 20lb battery, and our motors could sustain 8kw, then our efficiency w...

Re: Specific Climate Impact of Passenger Transport

Luckily, our favorite transportation choice on here is probably the cleanest thing possible. Electric drive converts energy better than humans do... even if the electricity comes from the crappiest coal this planet contains. Note that there is a subaru-robin 35cc kit out there that gets 200-250mpg o...

Re: An Advanced Friction Drive System

Count me in as someone who is totally stoked about this. I've been waiting for a system like this for a very long time and have been hesitant to invest in hub motors. I was initially thinking about hacking together a chain driven system with a clutch using go kart parts, but this is just so much mor...

Re: eBay special - good idea or bad?

700c are a pain. I remember having wider rims for my 15 mile non-electric commuter.. changing the innertube in the middle of a long country road SUCKED.. but nothing sucks like a 700c flat. I'm over it! Besides, 26" is generally the standard size for EV stuff. And i'm tired of the lack of options :|...

Yeah, i'm tired of pinch flats. Ready to get something with stupidly wide rims :) Also, it'd go flat in about 4 hours. lol. Wish i woulda known that when i forked over for the bike. Oh well, it was only $350. Kind of an entry level road bike. Yeah, not looking for crazy speed, just hill assist with ...

Re: eBay special - good idea or bad?

Yeah, i'd like to get a geared hub motor rather than a direct drive though. I like the lightness and efficiency of them. That eBike kit is compelling, but i think i shouldn't settle for less than the best, at least in terms of the motor. ( aren't some geared hub motors 12-15% more efficient? ) i kno...

I heard that the controller is super primitive and can be replaced with a on/off switch, lol..

It's brushed. Yeah. About as bad as it gets.

I like chain drive though. Seems like finding a good chain drive system is difficult.

Any potential for an eZip trailz?

Was wondering if anyone has ever taken an eZip trailz and attatched a brushed DC motor and better batteries. There are looking cheap to buy with dead batteries. I saw one on CL for $100 the other day and i was thinking.. hm, maybe this could be a cool start project; the motor and battery may suck bu...

Re: Post peak oil predictions

We'll switch over to EV power, biofuel, and CNG.

Viable alternatives exist already! It's only an issue of cost holding them back.

No mention if it's brushed or brushless. Trying to find that out first.

Re: Simple controllerless e-bike build

Yes indeed. Much better than the car forums i'm on.. :P BMC looks like another good option, but it's quite a bit more expensive than the ampedbikes kit; $200-$300 more O_O. Seems like it can handle more power and is built quite tough. i think that would be a good choice if i were overvolting. But i ...

Re: amped kit questions..

You should be able to use a rear motor on your AL frame. Especially on the lower power gear kits from Amped. The controller is set @ 14A. The Watt meter peaks at a little over 500w. Your rear drop out looks beefy enough for that kind of power. If you are still weary, you could add a torque arm to t...

Re: amped kit questions..

I could probably just find a steel fork for the front and use that, correct?

Are front forks commonly interchangeable, anyway?
