Re: eBay special - good idea or bad?

1. I figure the lead acid are just starter batteries. Because it would be my first eBike and all. 2. I'm 220lb and got flats on my bike ( Diamondback insight1 ) repeatedly. Someone hinted that this bike is for lighter folk. I figured this could plain just be the wrong bike for me. ( am i right? ) 3....

eBay special - good idea or bad?

Hey there. Remember me? the one with the 700c bike lookin' for a little hill climb assist setup, nothing full blown.. i'm 220lbs and don't need a long commute. Per mwkeefer's recommendation, i am getting rid of the 700c bike, and getting an aluminum mountain bike + installing a front steel fork + do...

You mean like that 36v 1000w motor meant for the scooter? O______O holy crap..

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

Re: Any potential for an eZip trailz?

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: The status quo of electric cars: better batteries, same

The model T got mid 20's mpg when it came out too. But it was a Model T..

Only thing holding back electrics is price.. which is dropping. ^_^

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.

$200 is nothing. Jesus Christ. Thanks for the tip!!

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..

Flat tires. They happen often on these skinny wheels unfortunately ( maybe the tires that came with the bike just suck though ). Just didn't want to connect/disconnect the rear wiring every time. And i was thinking weight balance would be a little better too. Rear should be fine though. And better f...

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?

Re: amped kit questions..

Why do you think 36v is too much battery? I'm sorry, i meant 60AH is more than i want. per studebiker; Does that mean that a rear one is acceptable, but a front isn't, on an aluminum bike? Here's what my rear dropout looks like BTW.. http://neptronix.org/reardropout1.jpg http://neptronix.org/reardr...

Re: amped kit questions..

^-- thanks, maybe i'll do that, washers + torque arms. Good lord, that 20ah thundersky battery is cheap. But i'd need 3 of them to make 36v and that's way more voltage than i want. What's involved in linking up lithiums to the amped kit anyway? just plug the batteries in? how do you monitor their ch...

Re: amped kit questions..

Advice taken. I'll forget about the rubber thing then. There is actually a good flat surface for the inner/outer washers anyway. My front fork actually looks fully formed as one piece, and the rear looks like a welded on piece, but they look equally as sturdy so i think i'll make this a front bike

Re: Simple controllerless e-bike build

I didn't know that geared brushless motors had an internal clutch, that's perfect!!! i don't want any drag after all. And i can't think of a way to do a chain drive system with a clutch without doing some major fabricating. I was actually thinking about going with the amped kit ( geared ) because th...

Re: Simple controllerless e-bike build

Yeah, i've been reading very mixed things about the magic pie setup. It sounds kinda funky IMO. I think i'm going to cross that one off my list unfortunately. I notice there are a lot of speed demons too :P.. IMHO, over 25mph is kind of scary on a bike so i'm not interested in that too much. I've go...

Re: amped kit questions..

Oooh. Nice. I like hearing that. Okay, so instead of torque arms, you've used washers? that's interesting. i wonder if polyethylene bushings would help at all? like motor mounts on a race car. Thanks for the advice. I've been obsessed with getting an EV bike since i first heard of them a year ago an...

With such little power, torque arms shouldn't be really needed... I've got 3 such similar builds based on another vendors similar hub motors in 26" and 20" varieties... I run modified controller at 25A/50A and normally 15-18S Lipo (55-66v nominal) without torque arms and notice ZERO movem...

Oh, and i have a 700c rim. It's a fairly light hybrid bike.

Re: Simple controllerless e-bike build

I just want a reliable, low power, low complexity setup. Something that is not intrusive, for sure. Just a throttle and small motor, because the majority of the time i will be pedaling for exercise. If that's possible with a controller, cool. But a lot of the controllers i see have connectors for al...

Re: Simple controllerless e-bike build

To be completely honest, i've been searching around the forums and it seems like programming/selecting a controller is no easy task. There is not much information, but a lot of jargon. I wish there was some kind of FAQ, because this stuff is intimidating. Since my electronics knowledge is pretty lim...

Hey there. I'm interested in rolling my own simple setup. I've been searching a lot on this site. I have a hybrid style bike with an aluminum frame. I figure this is the least desirable bike...
