I am in :) 18S LiPO has resulted 41-42 mph and 130V battery setup only 47 mph (small downhill). Max speed test can be seen on the first kilometers of this ride: http://www.sports-tracker.com/#/workout/olavi75/9ievmitnaur0btsm

Maybe 3 years ago I read a review of BionX in a local magazine and then I recognized, that I want an electric bike :D! The BionX was and still is quite expensive, therefore I started to look for alternatives and found this forum and eventually last year I selected components for my first build...

Lyen sells also these, I received one couple of days ago and the throttle is neither better or worse than throttle from ebikes.ca :)

Buying from Lau Chan seems to be like a lottery, some are lucky they have got a normal battery, others have got broken chargers, batteries with weak cell groups and Lau Chan has often just ignored the problem. You could read for example this thread...

You are following correct path, you can even charge two permanent 6s2p packs in parallel with a single charger, check this guide http://www.rcgroups.com/forums/showthread.php?t=932319 When batteries are in uneven charge state before connecting them together, then they will have the same...

Which would be the better deal, considering quality and reliability of the packs? a) Turnigy 5000mAh 6S 20C Lipo Pack, $59.99, burst 30C, 148x49x49mm, 793g, http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=9176 b) ZIPPY Flightmax 5000mAh 6S1P 15C, $62.02, burst 25C...

You could order a throttle from ebikes.ca also, replace e-crazyman's throttle connector and go. I haven't had any problem with this throttle and controller combo.

I live in Eastern Europe and buying from USA or Canada would be expensive due to shipping costs and 18% VAT I have to pay when buying from non EU country. Teamhybrid is in EU and I don't have to pay additional taxes and therefore I have to select a front Puma. A 48V 30-40A Infineon controller...

I think Fishmasterdan wanted to say, that geared motors have internal freewheels and they have almost no drag, when you pedal faster than motor (motor is switched off). Ezee motor is also a geared motor, direct hubs are NC and Crystalyte. According to Mark @ teamhybrid, he does not have rear...

I have read about people having hall sensor issues and I just wanted good reliability. Should I buy some spare hall sensors and go with sensored controller?

Hi! I am selecting components for my first 700C e-bike and probably I am going to order Puma motor, because it should have powerful torque and quite good top speed @ 48V. I am planning to start with 48V, but maybe later I will add a smaller booster Lipo pack to the 48V 20Ah LiFePO4 battery. I...

It is sad to hear you have got broken charger. Be prepared that replacement charger could be noisy, but at least it should charge pretty quickly. You could measure voltage difference on BMS wires, just measure voltage between BMS wire 1 and 2, then between 2 and 3, 3 and 4 and so on, or for...

I have received a Lau Chan's prismatic cell 48V 20Ah battery in the end of April and it came with the same PLC4806B charger. I measured the charging current and it was 4.85A. I have no motor yet, but I disharged the pack with 7A current about an hour and after this I measured voltages and...

Hi! Yes this battery is shrink wrapped, I payd about $407, delivery was included. Yesterday I tried the charger first time, cooler is a bit loud, but this could be fixed with a better fan. Before charging voltage of the battery was 53,7 V and in the beginning charger used 4,85 A current to...

Hi! I have also won an auction created by 2707co and after winning found out that the seller was mr. Lau. My pack was 48V 20Ah made of 7669130L 3.2V 4Ah (16s5p) prismatic cells with a 6A charger. Delivery was free and it took less than a week to get the battery to Europe. I measured voltage on...
