    Jetson Ryder Pro jry350-gbl water

    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.

    Ecotric Dolphin brake upgrade/motor cutoff

    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...

    Jetson Ryder Pro jry350-gbl water

    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...

    Sensored Motor Controller Wiring Manual Deciphering

    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...

    What have you learned from your e-bike experiences?

    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...

    Goodbye to biking

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

    Show Us a Tool

    15 bucks for a cable routing fish tool, huh? I looked on my wall and found a roll of weed whacker line. Pulled the 4:1 harness thru the frame with it and some tape,

    KT Contollers searching via model number

    I would think only the factory sells them by model numbers, and you probably need to order 1000 units to get their attention. The resellers that sell KT units have stocked models that are popular sellers. On the plus side, KT is a well documented brand with a variety of displays, and they are...

    Help with getting power from motor

    You built a really nice car there, but you do need to add some electrical skills. The alligator clips on your meter are a bit blunt for probing smaller contacts. Put them on your battery pins first. That will help show you how to use the meter.

    Help with getting power from motor

    RIght. Top comes from controller. POwer comes in on red/black. Check that first, When display turns on, it sends power back to the controller on the blue, Two plug connector is still probably for lights, Very low current, when you get the display working, DOn't power the lights directly. Use a...

    Help with getting power from motor

    No display lighting up means it's not seeing battery power. It gets battery power from the controller. I believe it's this connector. What you circled is for lights. Here's how it works. Red and black from the top are battery/ground., Check it for your battery power with your multimeter. It's...

    And todays morons are

    What to watch for is the jogger/walker ahead of you who decides to do a 180 degree turn and come back at you, jumping into the lane you were planning to use to pass them.

    Screwed up

    Bought your old ebike back? Hmmmm. They're supposed to throw it back at you while cursing your children and pets, so you get it for free. Then you bought a VannMoof? Nice! That's entropy, N+2.

    Presta valve material

    An after market sensor on a car has to be (a) real tight and (b) sloshes thru rain/slush 24/7. My adapters are on finger tight. The valve stem underneath is screwed down to hold the air, and they always leak, hence a check before almost every ride, Plus they don't see winter conditions when...

    Help with getting power from motor

    You put it all together and it worked! Hurray. Then you extended the wires. Doesn't work. That's a logical place to start looking I'm sure you did, but keep looking. There's also different classes of not working. Does the display turn on or is it blank. If it turns on, does it give an error...

    hi, new Lectric dude from the Chicago area

    The lake path can be quite busy on weekends across from downtown. Yes, I think it's fun and scenic. Expect to drop some bucks on parking and a slow drive home on the expressways at the end of day, You could park up north some place off Lake Shore Drive and ride to the path. Or start in the...

    Presta valve material

    I've kept brass Shraeder adapters screwed on the Presta tubes on two bikes for ten years now. They're always being screwed on/off to check tire pressure. Never worried about them binding,
