I see the GF25 advertises a battery with Lishen cells. Lishen is a major Korean battery maker, not a small time supplier of junk cells, so that's a good thing. I've not heard of Yadea, but yikes, if they sell a motorcycle like this, they must know how to build a dinky 250W mid motor...

First you have a battery that won't charge. It is also losing voltage. It's also warmer than ambient temperature. You can't fix these things. or you shouldn't try. Any battery that self heats is dangerous. The only component in the pack that should get warm when idle is the BMS, and that's only...

When you buy a KT controller, it will max out at the amps rated on its label, but it's really intended to run at half that value for continuous running, WIth a KT display like the LCD3, you'll see the actual wattage on the screen at all times. A 17A model on 48V will peak around 850W if you...

One of the cells could have deteriorated and become a heater. Very dangerous to recharge or use. If you can feel 36C at the case, it must be pretty warm inside, enough to trip the Specialized thermal sensors which I would expect then to be using, You're right to drop it off at the shop...

Chain is a "little loose", but you haven't addressed that? Take out a link. See what happens.

Yes. I run a 25A controller on several ebikes. One of them would melt if I were stupid about riding it. Just don't be stupid. .

What's the axle width of the XP Lite? Is it 135mm like many fat tire bikes or 100mm like regular width tires? These forks are 117mm.

We don't have fat tire folders anymore, but have folding ebikes that we never fold. For transport either inside a SUV or on a rack, it's convenient to have folding pedals, It keeps them from scraping things. Sure, upgrade to better folding pedals or quick release pedals. I've considered putting...

To restate your problem. The throttle quits working after a minute of using it while riding uphill? How fast do you like to ride the bike? Do you pedal it too?

Are you in Canada or Europe? That's your typical high power motor from China. You could look all day and find them all the same price. It might be better, if you''re in Canada to look on amazon.ca and find an importer in your country or in the USA. I think Ebikeling has an OK reputation on...

Yep. They came to "serve Mankind."

Come on, My motors have nothing in them to prevent overheating, and if you send an EMP pulse big enough to stop a controller, you will have fried it. Also killed the BMS so that battery will blow up next time it's re-charged. Probably whack out my pacemaker too and speed up my insulin pump, if...

My brother had an italian single cylnder Ducati motorcycle and I had a Suzuki, The rear brake and the shifters on those motorcycles are operated by your foot, and these were on different sides. Many is the time I would want do a panic stop and be mashing the shifter instead of the brake pedal...

The US Consumer Product rules say "Unless a customer specifies otherwise, the hand lever that operates the rear brake must be on the right handlebar." That allows the bike shop to move it, but it's going to ship that way. ,

Round molded connectors require a DIY mentality, You can figure out that yourself, I will leave you this diagram for the 9pin motor connector if you have one. First. make sure it's seated properly. It's keyed, but some people have ,anaged to force them in backward and fry the controller. You...

You never mentioned what kind of connectors on the Ancheer controller. Whther it has the flat or molder connectors. The latter are difficult to access. If you have the cheaper ones on the left, which I would expect on an Ancheer, you could stick pins into the back of each connector to reach...

Most of the reviews are negative. Why try to prove them wrong?

The motor wattage is proportional to the voltage. Your 36V pack is 42V at full charge and will drop to around 30V. That's like a 30% swing, It can't go much lower than 30V, because there are safety cricuits in both the ebike and in the battery that will shut it down, With experience, you'll...

A typical front hub is 100mm wide between the forks. A typical rear hub is 130-140mm, with most at 135mm. The extra width is for the gear cluster, and even if you removed it, the rear motor usually wouldn't have enough threads on the axle to engage the fork. The only time I've been able to...

Specify the tire size. 20" x 40mm, 20" x 4" or something in between? Folders also come in 26" x2" tires, and also 16" x skinny tires. I can't get excited about a folding 20" fat tire bike that weighs 65 lbs, I had one that I never folded. I could have had two of them for $1500 as my final...
