http://www.modernbike.com/itemgroup.asp?igpk=2126179496&TID=367&gclid=CPWW-ZazvrkCFYqZ4Aodcz8AxQ I have these 140mm cranks and they cleared with room to spare. They also give you more ground clearance so if you use a 20 or 24 inch wheel you can pedal through turns and not have to worry about...

The motor is a new (had maybe 200 miles max on it) hs4040 from ebikessf so the axle is fine. The axle was resting all the way in the front of the slot (as deep as it can go, towards the front of the bike). Block time was set to 0. The swing arm is from the first batch. It was actually bought...

First of all I'd like to say I'm not bashing farfle in any way just want to post this so people can avoid the problem that I have... I posted my bike a while back when I was just starting to build it. I'm still working on it but I have been riding back and forth to work on it a few times over...

I had a similar problem with my yescomusa dd hub motor and 12 fet crystalyte sensorless controller. Same issue except I started seeing problems at around 25mph. Same deal: if I was easy on the throttle I could avoid it but WOT throttle would produced the horrible grinding. I never solved the...

I work at UPS from 4-9AM, the "preload" for anyone who is familiar. I go to community college and I'm trying to figure out exactly what to study. I'm thinking computer engineering. All I can say from my experience at UPS is, don't ever ship anything in such a way that you would not feel...

I'm not sure. My chain isn't long enough to test it but I think you could. You could also weld a derailleur on it or a dr. bass torque arm with a derailleur tab

The farfle swing arm is incredible. The dropouts are extremely solid. This is my chain setup I had to put a few extra links in the chain for it to reach. I was able to adjust the chain tension pretty well because of the horizontal dropouts. I was forced to use the smallest chain ring on the...

Someone sent me a pm asking me a few questions about my setup so I'm gonna answer them in this post here. First, my bulk charging setup. I have two of these power supplies: http://www.ebay.com/itm/251239457968?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 They are 32-40. Very easy to...

Sure these pictures should give you a better idea. The camera on my phone is decent but not great with the light I have so this is the best I could get for the moment. Three bolts hold it against the top tube: One bolt in each corner, here is what I mean by that: All of these bolts are...

Alright I posted about a year ago asking for some advice and I've been tinkering away ever since. After much trial and error, I have created something that I don't feel ashamed to post here among the other awesome bikes that read about all the time. I started with a walmart hardtail with a...

Wow glad I asked before ordering. Looks like I'll be ordering the 48v 15Ah battery now, the range is more important than the speed to me, especially on the bmx frame. Haha looks like I'm off to sell some more old junk of mine on craigslist I'll post back here when my orders start coming in and...

Sorry to revive a thread that's a bit old but I've done some more research and planning and I think I have everything finalized for real this time (probably not). Alright so after much deliberation I found that lipos are probably not the best fit for my project. They require more maintenance...

Alright so I did some more reading and took into consideration some of the input I you guys gave me. After thinking it through, a 25mph top speed seems a little more sensible and is something I can definitely deal with especially considering the legal aspects of it. I'm going to college in a...

Thanks for the tip with 8Ah instead of 10Ah and all other variables the same, the new top speeds are pretty much the same and range has gone down to 8 mi at 100% and 12 at 75%. Still acceptable and I'll probably buy more batteries as soon as I have enough money anyway.

Alright here's the new complete parts list: From ebikes.ca -infineon 36-72v 40A controller 175.00 -crystalyte 3548 in 20 inch wheel 395.00 -throttle 20.00 -cycle analyst with spedo 125.00 so that's $814.00 with shipping so far from hobbyking: - 8 x 5000mAh 4s1p 14.8v 20c lipo...
