Golden Motor E-Bike Conversion

I converted my Costco bike to an e-bike using a Golden Motor 48V 1000W rear hub kit from Golden Motor Canada (buy from Gary at GM Canada if you want exceptional customer service!). Top speed is about 45-50km/h, although I have gone a little over 60km/h on a slight downhill.
Specs:
- 26" rear 1000W hub motor
- External controller
- 48V 1000W 12ah lithium-ion battery
- Twist Throttle, cruise control, reverse switch, horn
- Top speed ~50km/h on flat, no wind, fully charged, rider 170lbs, tires 65psi, slight tuck
- Range: Theoretically ~25km, however, I have yet to completely discharge the battery but it seems that with normal city riding and no pedalling it will go ~15km
-acceleration: on full charge, estimate about 10 seconds to go from 0-50 (same conditions as in top speed test)

Any questions let me know!

I just watched all your ebike vids to your final setup up. I've been doing some research on other conversion kits and this one seems like the only one that does not die in two months or being overpriced. I'm planning on buying the same kit as you show in this vid from GM. My one question is there a advantage having the motor in the rear wheel instead of the front?

Thanks for the video,

Richard

@Urlte Thanks for watching! I tried to document stuff that I thought would be helpful if someone had to go through the same build. To answer your question, there is only one advantage that I can think of for having a front wheel motor instead of rear and that is simplicity of installation and removal. Other than that, you want to have a rear wheel motor if at all possible. 1: It won't slip when you need torque, ie. when going uphill. 2: Front forks are very weak and can break from all of the

@Urlte motor's torque. If you lose your rear wheel, you will still live. If you lose your front, not so good... Also, most front forks are made of aluminum. If that's your case, then forget about a front motor. Even steel forks give out eventually, but at least the failure is gradual and you can catch it with regular inspections. 3. Less distance for the battery/controller connections (assuming you use original kit's rack and controller box) 4. this one is debatable but you get better weight

[mike66266]

@Urlte distribution and therefore it's easier to control the bike. I think there were a few more reasons why rear is better than forward but that's all I can remember at the moment. It's discussed quite a bit in the ebike world so you might be able to find more info. Best of luck with your build!

Cool bike!

How is the suspension holding up at high speeds?

[mike66266]

@FullFledged2010 Thanks!

The suspension works really well actually. I used to go past 60km/h on some downhills before I put on the motor and one time I hit a huge pothole and it went over it smoothly so I knew this bike would handle higher speeds just fine. The only thing I worry about is snapping spokes.

@GoldenMotorCanada Hi Gary,

My bad for forgetting to mention that in the video, I just kind of blabbed away without really thinking as is evident by all the "ah's" and "uhm's" :P I did have a link to your site in the description but I've also added it in that I bought it from Golden Motor Canada at the top there.

@mike66266 Hi, I bought an almost exact kit and am having a bit of trouble. Do you mind taking a look at the pm I sent you? It has a link of the video showing what's weird.

Hi Mike!

Glad to see things are still going strong and the bike still looks great! One thing you forgot to mention was you bought it from Golden Motor Canada :)

I had one of the original GM motors when they first came out. The motors themselves were good, but everything else was junk. The throttle broke and the rim was nowhere near strong enough to handle the weight and speed of everything. Mine Tacoed within a month of riding it. It looks like they have improved the kits since then
