Is a replacement axle for HS3540 available for purchase anywhere?

Here are the updates! I"ve cleaned up the bike and drop out. And YES, the problem was with hall sensor. I"ve replaced all three just in case, I'm surprised with how clean the inside of the motor was despite all the riding and harsh conditions in the last three years! Here are the photos! Almost forg...

Okay, Its been a while since my last update. I run into trouble last week...My ebike has finally given up on me on way to work... I was going about 30mph when light changed in front of me so I let the throttle go and regen kicked in, I hear grinding noise just like when sensor wires aren't matched a...

Just installed everything here and I used different torquearms.. Now I am having the same problem as you did earlier.. the BB :D Which one did you buy? ~ the 52t.. I have 4-bolt chainrings though, so I don't know if it fits Sorry I didnt get back to you sooner. I had trouble logging in the other da...

How are Doc's torquearms holding up with the dp410? I just bought a 2008 Epic comp and planning to do the same as your dropouts 8) Thanks m8 After over 3000miles, still holding solid! Only thing I've done is to paint it with anti-rust paint so I try winto rust away. Just make sure you heat it while...

before you decide I'll tell u something from my experience. my first E-bike did have battery pack on the rear rack. it was so out of balance and I never got satisfied with how it looked. plus you will never find perfect stand so it will fall once in a while. if lipo is not protected very well, you c...

As far as balance charging, hows your cheapo ebay one working? Do you think id be okay to bulk charge and use 3 battery medics (6s3p) kind of like what you did with 4? I can easily make 3 harnesses for the balance leads. Cant say I really understand why you use the battery medics to balance out the...

1. Current configuration and parts (motor, controller, battery) 20s2p (83.5v 10ah Lipo),HS3540 sensored (MethTek), 12FET lyen @ 50A 2. Top speed and distances Top speed 45mph(72.4km/h) 3. Total bike weight 32kg. I've got most of how i set up the battery packs on fisrt couple pages of this thread so...

thanks!

I've started sort of new life in Japan away from UK now so dont have time to update...
BUT! I"ve bought back my bike with me and is already assembled back! so will do some updates in next couple weeks!

yea! that totally happens to me too! I've always wondered if there are any ways to solve it other then to go slower....

I'm leaving UK very soon and I'll continue to make some videos and the updates but for now...
I am selling my bms chargers so check it out if you live in UK!

Hi, I've got some c4140 transistors for 600w charger replacement.
Questions is, can I use them for 400w charger too? The 400w ones are 4139.

I think for you. the best thing to do is to buy kit with 48v 1000w motor, 25A controller and 10/15Ah Lifepo4. most of the ebay kit with battery are this type. this is good example: http://www.ebay.co.uk/itm/1000W-Motor-48V-15AH-Lithium-Ion-Battery-Electric-Bicycle-Conversion-kit-/390594910673?pt=LH_...

1. Is there any reason I should wait till I have a bike before I spring for the rest of the gear? Dropout spacing maybe? 2. Recommendations on a balancer that would work with my large lead acid batteries and accommodate my large amount of laptop battery cells in the future? 3. How many amp-hours do...

+1 I like it too!

Sorry to change the subject but what freewheel / rear gear do you have there?? it doesn't look like normal freewheel?!

Easiest way I know is to use heatgun/hair dryer. that’s how Fox mechanics removes old decal to new ones when they service customers fork.

I hope this works on yours too

No, That bike has no motor, controller, battery, brake/gear cables, brake levers, suspension and derailleur. I may have missed more

pretty cool stuff. Few things I've noticed. they haven't got anywhere near finish...they need to make the bike functionable before they start converting it to electric. At their stage, no brake, no gears, no lights and no suspensions. With extra weights on the bike with battery, motor, controller ec...

I just PM'd for a set too :-) It's only a direct drive 36V 500W rear setup from Vpower.hk so not all that powerful anyway. My bike is a cheaparse Milazo full suspension, all steel. From that I can confidently say you wont need torque plate as strong as this one... but If you want one for the future...

I know some people must have thought about this but has anyone attempted to make a use of peltier? I think instead of trying to use ambient temperature to cool hub motor, we should be using something which is cold to cool hub motor. since the hub is designed to spin, we can use the peltier to cool d...

Hey All - another sad BMS Battery Alloy Shell Charger owner here. My 74v 600W unit smoked itself last night, and for no good reason. No abuse, kept a room fan blowing on it, they stayed inside and never got exposed to bad weather. I'm reading over the thread now, will try to figure out if I can fix...

something very annoying happened today... my bulk charger died again (3rd time). this time, cheap chinese resistor decided to blow up 5min into charging... IMG-20130503-01445.jpg Having BMSBattery charger gives me a good reason to balance charge individually every now and then :wink: I'll replace it...

oh! I forgot to upload the final build pictures! here you go!

Here is a Looong waited new ebike video!
this is completely finished build of my 5th ebike! since the frame is lighter my acceleration feels so much better!
