I have decided to change tack - again - on this project. I originally bought an aluminium alloy frame MTB that I intended to convert to an ebike. Since then, I have set that bike up so well that I really enjoy riding it with pedals only. After a long think, I have decided to buy a cheap(er)...

HarryS, thank you for the warning. Rather than use the rear rack shown above, I purchased a different type with a higher load rating for USD20 (incl. delivery from Manila). This rack is rated for a 25kg load. I loaded it to 80kg (static) without any noticeable deformation, so it should be...

With gel type lead acid batteries, which is correct? 1. Charging = Exothermic Discharging = Endothermic 2. Charging = Exothermic Discharging = Neutral 3. Charging = Exothermic Discharging = Exothermic 3. Charging = Neutral Discharging = Neutral 4. Charging =...

Thank you to all for the advice. I understand about connecting batteries is series, 4 x 12V 16Ahr = 48V 16Ahr. I have decided to buy the 4 x 12V 16Ahr batteries (4.3kg or 9.5 lb each) for USD97 total incl. delivery. I already have a 48V 20Ahr charger to use with these batteries. Each...

I understand that I will need 4 x 12V batteries. What do you mean "Run your controller at me more than 15."? Unfortunately the cost of Li Ion batteries are beyond my available budget.

I live on a relatively flat island with a circumference of about 26km (16 miles). A typical daily ride for me would be at most 20km (all sealed roads) with about 2km of 1% assent, 2km of 1% decent and the rest on the flat. Average speed would be about 15kph (9.4mph). Due to traffic congestion...

Here is a photo of the rear dropouts on my MTB that I am converting into an ebike (axel nut and washer removed for clarity). I have designed a stainless steel torque plate (one each side) that will bolt onto the dropouts. These torque plates will hold the hub-motor axel about 1mm away from...

The only broken dropouts that I have seen on ebikes have been in China. Most had broken lugs (although some had broken elsewhere) and all of those broken lugs broke where the axel shoulder had dig into the lug at or near the start of the semicircular part of the lug cut-out. These dropouts where...

AHick, you are missing the point. The problem is not that the hub-motor axel is not seated fully into the lug cut-out. The problem is that the sharp shoulders on the axel cut into the lugs. Any sharp corners (or cracks) in a stressed member concentrate the stress at that corner. Filing (or...

I am working on fitting an ebike kit to my MTB. The kit is based on a 48V 1000W non-geared rear wheel hub motor. The MTB has an aluminium alloy frame (including dropouts). During my research on this project, many articles recommended that the axel of the hub motor be fitted with a torque arm...

Congratulations ngolm. I am going through a similar project with a 48V 1000W conversation kit on my aluminium framed MTB. Still many problems to solve but it is all part of the learning experience.

So far, I have not had much free time to play with the conversion kit. I played around with the handlebar controls and am satisfied that I can position everything to my liking. A couple of spokes on the hub motor wheel were loose so I had my local bicycle mechanic reset all the wheel's spokes...

I was originally going to use this conversion kit to electrically power a Filipino style pedicab. After posting and getting advice from members here, I realised that I had a lot more to learn so decided to postpone the pedicab project and first convert my 26" MTB to an e-bike. The conversion...

This forum is awesome. With your guidance I have saved myself a lot of headaches. I think it best that I put this pedicab conversion on hold for a while. I will fit the 48V 1000W kit to my 26" MTB first to learn more about electrically powering of a bicycle. With more experience, I will then...

Thank you for the input. I was wondering about what you have raised. Unfortunately, the purchased hub motor is a fixed deal that cannot be changed. If I cannot use it on the pedicab, I will use it on my 26" mountain bike. Do you think what I am trying to do with this hub motor on the pedicab...

Now that I have accumulated a bit more information on this project, I will start asking some questions. The pedicab is to be pedal assist, meaning at startup and possibly on inclines, the driver will also be pedaling. It also needs a range of about 40km on flat terrain. Although not yet...

Hub Motor Specification The kit is sourced from China with a recommended price of about USD360 + shipping (about USD10 from China to Cebu, Philippines). I managed to buy it on special at USD255 including delivery. The kit package includes: 1 x Motor wheel (inner tube is not included) 1 x...

Thank you for all the comments so far on this project. They are much appreciated. I am treating this as an engineering project, so the first job is to gather as much of the needed information as possible. Once obtained, I will then start looking into who the project can be executed and address...

The following are some photos of the pedicab to be modified. LH Profile with the driver Erwin in the background. That white animal bottom left is the only girl who truly loves me unconditionally. The motorcycle is my Yamaha YBR125G. RH Profile Front Wheel Left Wheel Right Wheel...
