A very nice find, and worth 250 bucks, You could probably rebuild the battery as a 28V12AH 9S-4P and have a little more power w/o blowing up the controller.

Nice bike for city traffic. Might get some respect from other drivers. That's when I like riding my fat tire 26 incher, It's probably a generic battery in that frame. You can't make any money having to source a one-off battery case. If you buy a spare, make sure they use good quality cells.

I have a handlebar USB accessory jack on one bike. After I installed it, my wireless computer couldn't get a signal from the wheels. Probably interference from the DC-DC converter inside the accessory, Some ebike displays likely do the same thing,

The last two racks I owned used metal loops to hold the wheels. Wheels would be well secured by gravity, but you wanted to use the velco straps to make sure they stayed in place. I learned later that if you get a big nylon tie strap, it can be used to wrap around the bikes in the middle of the...

Well, if you still have the battery cannister, a re-cell service could transplant the cells and circuitry from another battery into it. Not a hard job,

Is this your bike? Unfortunately, it uses something like the common 36V Silverfish battery but not quite the same. Doesn't use a rear strut and the key is on the wrong side. so it must attach quite differently. I doubt that you're going to find a replacement, You don't have the old battery...

Here's a cheap Cruiser I did in 2018. Bought a used bafang front motor and a used 36V nineboot scooter pack for $100. Motor controller was $75. Put it on a Kent 26" Cruiser. Rolling along for under $200. Later went to a 48V battery, upgraded the awful rim brakes to disk brakes, and am at...

Have you tried torquing down the pedal arms, replacing the pedals and finally tightening the motor mount screws? I've found all kinds of noises from pedalling in my bikes were based on something loose in the above three areas. I suppose a good bike would have tried these things.

I got the motor so I wouldn't have to stand up on hills. Ugh, the bad old days when I would crest the hill at 6 mph, standing while pumping the pedals for most of it. Like teskow, I still stand when I see bumpy stretches coming,

Lithium batteries use a battery management system (BMS) for safety. The BMS monitors all the cell voltages. If any are too low, it opens a switch on the ground side and the internal cells are isolated from the outside. When this happens, you won't measure any voltage, other than what leaks thru...

This sounds like a Hall sensor problem. They're inside the motor. Falling over should not affect them as they are tiny. PCEbiker put up this nice pic of his motor the other day. You can see three of them on the outer edges of he circuit board. What could have happened is you knocked the motor...

Unplug the controller from the battery, if you can. Then measure the battery voltage at the plug with and without charger plugged in. Want to know how battery is behaving with no load on it.

I've added switches to the MT200. Basic kit is a round magnet with a hole in it, and a plastic switch box with a normally closed switch. When a magnet is brought close, it opens. I mounted the magnet on the aluminum lever with epoxy. The switch box uses double sided foam tape, but I added extra...

Specs say 36V battery. That means a max voltage of 42.0 V at full charge. The scooter will run til the battery gets to around 30V. Then the scooter shuts off. The battery has its own shutoff that triggers slightly under that, as a fail safe. Running a lithium battery too low can damage the cells...

I've always set my speed limit in the display at max, so never had to worry about the bike surging at the limiter. Given my age and how my bikes look, I never worried about being stopped for bike checks. I do have a problem with external speed sensors on my KT controllers though. Have put up...

It's over rated. Soggy dog under the junk, but great milk shakes, All milk shakes are good,

Rarely stop to eat on a bike ride unless I pass Superdawgs.

Ebiking has allowed my wife and I, both of us over 20 years older than the OP, to enjoy biking daily. We put on over 17K miles riding together in 10 years. We don't need a lot of ebike to ride on our local path and on rail trails. Have learned that even with an average speed is 12 mph, long...

Steerer tubes coming out of the forks? Not on a Giant!

Haven't biked all month. Came down with Covid on 6-30. Too tired to do anything. Lot of sleep time. Maybe next week.
