Could BMW sell the concept of a speed limiter in their cars based on the cars location to their customers? I think it is a bad idea and wouldn't buy one. This is not to mention the slippery slope of the possibility of your bike tracking your movements storing it in a black box.

The controller is built into the BBSHD. Luna sells replacements for the BBSHD controllers.

One with a Bosch motor might be hard to find. There are plenty with a Bafang Ultra motor. WW Hydra, Biktrix Juggernaut FS, Luna Cycle Apollo, Frey AM1000, etc

I am not familiar with that bike. Most throttles use hall effect sensors, but not all of them. There are usually three pins (ground, +5V, and signal), but sometimes the throttle has other functions such as a battery level display or a cutoff switch and there are more pins on the connector. Even...

If you google "bicycle fender bridge" you will find some that might work. You could also make one with a coat hanger.

It would cost them more to pay their accountant to create an invoice to bill you and process the payment than the actual cost of the electricity. Common sense isn't very common any more.

A higher Ah battery will give you more range, not more power. You would need to replace the controller to feed more power to the motor. That is assuming that the battery's current rating (C-rate) can handle it.

It is not actually a problem. He ran the battery down to the low voltage cutoff and the motor shut off. Once he charged it again, the battery was fine. He got 39 miles on a 905 WH battery (assuming the manufacturer claims are accurate). That is 23 WH / mile. While high, it is not outside the...

I don't mind enabling you: Exercise - Light and low powered: Specialized Vado SL, Creo, or Trek Domaine? Mountain bike - Full suspension with a powerful mid-drive like the Bafang Ultra: Rize RX, Juggernaut Ultra, or Hydra Commute to work - Upright bike with rack, fenders, and lights Sand and...

Many people buy a second battery for longer trips or bring a charger with them to bump charge at rest stops. The battery's range will decrease with age and also in cold weather.

42V should be around the low voltage cutoff of a 52V battery. I would guess that is why it shut down. If you have a temperature sensor in your Bafang (BBSHD?), then the controller might have shut it down due to overheating to protect the motor. The BBSHD shouldn't overheat on a 10% grade if...

Here is information on what blank is needed for a replacement key: https://electricbikereview.com/forums/threads/resource-thread-battery-keys.23195/ MTA: Also, with the missing charger and missing key, it is possible that this is a stolen bike. You might check with the police department if it...

Another option is to move the Bafang motor kit to bike that fits you. You can pick up good donor bikes on Craigslist for $200-300 or you might have one in your garage. You still have to figure out the battery voltage or replace the battery if you do that. A lock smith could probably take care...

If you have a multimeter, you can measure the charge on the battery. However, 48V and 52V batteries have some overlap in the range of their state of charge. If it is a 36V battery, it should be obvious. People don't usually run Bafang mid-drives at 36V though. 48V is the most likely, but it...

Flying cars aren't going to happen in what is remaining of my lifetime. Pre-Covid, I thought that self-driving electric taxi services were the future around metro areas and perhaps the surrounding suburbs. That effort seems to have died off due to less demand and the safety/danger of...

Honestly, you might be better off buying a new battery. It sounds like that battery wasn't well cared for. If you don't keep a minimal charge on it, it can ruin the battery. It is hard to tell what the voltage of the battery is from that picture and your description. An expensive option would...

Ebikeling sells that display. I would contact them to buy a new 48V controller.

These people are on a tight budget or maybe it is just a toy that they don't want to spend too much money on. However, when the $1500 bike breaks they will want it repaired or it will just sit in the garage and never get ridden again.

There are a lot of things. Here are a few off the top of my head. The obvious: voltage of the battery and the watt rating of the motor Brushed or brushless motor (it is most likely brushless) Hall sensors in the motor (it probably has these) Temperature sensor in the motor Cadence or torque...

Maybe. People are reluctant to pay $50-$60/hr to repair a $250 bicycle. Sometimes it is cheaper to just buy a new bike. However, that isn't too steep for a $2500 bicycle. A lot of us work on our own bikes, but not everyone can or wants to do that.
