    BIG BLOCK alternative Motor

    A slotted axle. :? The GNG big block has built in gear and if you cut the gear the axle still long enough. How are you going to fit a sprocket int that axle?

    mid sized motor?

    That is GNG gen 1 small block motor, you can buy one from lightingrods, but you can't directly drive the rear wheel because you need more reduction gear ratio. The big motor me0907 can drive the rear wheel directly because it is a motorcycle mid motor and is powerful, but fitting in a bicycle...

    Which Chinese scooter to buy?

    :shock: You know you are in Canada, we have so many rules regulations here. If you import a high power one, it is hard to get it register and insured. You will also having hard time finding one that is 500w and under, all the scooters here are specially made/labeled to meet Canadian regulations.

    mid sized motor?

    I am also looking for a mid size motor directly drive rear wheel, but not a lot of options. BHT 1000w motor seems to be the most popular here. Goldenmotor also has a few 500-800w but not great. Headline motor from cyclone / sickbikeparts 650w come with gearbox. Gen 2 GNG 500w motor also has...

    Cheap Vietnamese eBikes.

    So , is Vietnam banning all gas engine motorcycles like China? Gas ones should be cheaper to run. Are these ebikes imported from China or made in Vietnam?

    BIG BLOCK alternative Motor

    Good idea to modify the motor shaft. 5/8 sprockets or very easy to find. That reminds me people modifying GNG v1 to chain drive. You can run the motor and put a file on the shaft to grind down (Can't find the page though :( ) But cutting a keyway would be more difficult.

    ELTEK Flatpack2 48/2000 (eaton alternative)

    I thought it would be similar to the MeanWell power supply with voltage and current mod. This one is not to use as bulk charger and must be used with other controller. Good/bad thing is that I didn't win the bid on an ebay one. :mrgreen:

    BIG BLOCK alternative Motor

    Yep, seems 14mm ID sprockets are hard to find, most common ones are 1/2 and 5/8. Other people either build their own or weld another on the old one.

    What kind of ebike is this?

    1. The motor is geared motor, so it is normal to have more noise than DD motor. 2. Get rid off the lead acid batteries, it will save you 30lb. But you will need to get your key first. 3. Disconnect peddle sensor to the controller. Your thumb throttle will not work unless you stop peddling...

    What kind of ebike is this?

    A Canadian Strong bike, still sold in France as ISD Futuro/ Explorer/ Excelsior. Since you are Canadian, you can find one locally at pretty low price. It looks good on picture, but it is not very "strong" bike. The motor is very weak, the controller has 45v and 17A max. The whole bike is very...

    Voltmeter/Ammeter Question

    like most wattmeter, the + only show the voltage, the - use to measure current. So the shun must be on the negative side.

    ELTEK Flatpack2 48/2000 (eaton alternative)

    Can you adjust/limit the current on this power supply? 37A is too much for most battery packs.

    Snapped off my rear dropout!

    Aluminum is not good for torque arm, too soft. If you have skill and tools, you can make a steel plate and bolt on your frame. But it looks hard since your original dropout slot is gone.

    Battery Case Specs E-PCASE09

    laptop cells are never good in this application due to low current discharge 1-2C. You can fit 10s5p, 12s4p or 14s3p inside. so you better use high power cells.

    Is 200 USD for shipping 6 kg from China to Canada?

    They have to ship as battery package. So, you heavy motor also count as battery shipping cost. If you buy the motor only then they can ship as regular parcel. BMSbattery don't seem to have sea shipping option, but some ebay seller ship battery by sea, may take 2-3 months.

    New build by newbie, does this look resonable?

    You can go with Magic Pie 2 external controller. It is even cheaper than Magic Pie 3. Older bikes may have 128-130mm drop out. I spread mine with car jack to 135mm but seems one side goes out more than the other :cry:
