    People for Bikes: Progress on Ebike Laws in the US

    I was up in Charlyvoo last May. Had visions of endless miles riding along the Lake Michigan coast, but the reality is most of it is private land. A mile or two in a State park is as good as it got. Anyway, we had class 2 ebikes, and I believe it's still no throttles on paths, No one cares...

    500w/48v15ah battery What is the correct speed?

    The bozo is riding around with a dragging brake. I hate to give these shills (have a channel - get a free bike to "test") clicks because it makes money for them. Probably around 24 mph. The gearing on these 20 inchers is such that you run out of pedal speed around 18-20 mph, even if you are...

    Some bicycle travel tips

    Last Spring. after we checked into our AIr BnB and read the rules book, we learned no bicycles at all in the rooms. It was about dirt from tires, grease on carpet? Fortunately, we had a nice screened porch on the 1st floor. I put our two bikes there. AC wasn't working and managers and workmen...

    Is it the battery ?

    Well, you need to determine whether this is just a one-off event or if it happens every time you go out. The first case is likely a contact or connector issue. The second is systematic and is due to a faulty battery, It's likely an unbalanced battery. If you can find a local Emojo users group...

    BBS02 ebike shuts down while riding

    In my opinion, probably the battery. Make sure your meter is accurate, Check it against your charger, which should be 54.6V, If your bike is shutting off at 52 volts. it's likely to be severely unbalanced. It should run down to 40-42 volts, Maybe a friend has a battery you can borrow, That's...

    2017 GB1 Controller LSW905-27-1 Error Code 9

    Yeah, I think error 9 implies a bad controller, The display isn't hearing any messages from it, I have been buying KT controllers all this time (8 years, many controllers) and I just realized that they don't have an error code for the above comm errors. In fact, the list is pretty spares. Some...

    Consumer Reports: Ebike Fires

    Is it the battery ?

    Randroid has to determine whether this is an intermittent problem or a systematic one. It sounds though that he wisely heads home after the shutdown and puts the bike on recharge. It will take about 30 minutes and the charger goes green. THen if he goes out later, it will happen again, That's...

    Uck1 display

    That's probably a 3 pin voltage regulator like an LM317, but don't take that to the bank. Could be a MOSFET too. You'll want to read the label off a good UCK-1.

    2017 GB1 Controller LSW905-27-1 Error Code 9

    Error codes are specific to the display. Look at your display model and google for a manual on it. Being that your control starts with LSW... that is probably a Lishui controller/display. Then you can see what Error 9 means. I see no display on your handlebars though, It must have one to flash...

    Is it the battery ?

    Max charge for a 48V li-ion battery is 54.6V. A little less is common. Your 52.4 could indicate an issue. Check your charger voltage, That should be 54.6V with nothing connected, and this will serve as a calibration of your meter, Loss of 1 volt from full charge during a short run is typical.

    Anyone know any thing about this Lightest e-bike motor kit?

    This is an Italian group who have been talking up crowdfunded middrives for around 8 years now. This is their 3rd or 4th iteration, earlier ones never getting to market, Go to this thread. It started in 2018, but this takes you to a year ago when they started shipping the first of the latest...

    Glad to know your Valentine's day bike from 2022 is still working out for you.

    After a month of riding ...

    Your P02 enables cruise control, There is some other mechanism on your bike to use cruise control, On my bikes, holding the throttle constant for over 20 seconds does that. Probably the same on others, Doesn't increase speed.

    Battery has weird values from different sides

    In the second video, where you switched the red/black probes around, it's clear that you didn't put your probes on the same spots in both videos. You moved them to the opposite side of the battery and who knows where you were measuring. If you're going to prove that flipping the probes around...

    After a month of riding ...

    In general, I think a $1299 fat tire ebike with geared typical hub motor and 48V battery doesn't need a speed limiter to hold at 28 mph, since that's around the top speed anyway. You'll get a little more and every little bit helps, but 35mph needs a lot more battery. Good luck. Nice looking bike.

    Is Any E-Bike With A Throttle A Type 2 E-Bike?

    Some localities have resolved that "Klass 3 mit gaspedal" shenanigans by making all throttles verboten. In Illinois, the three classes are clearly defined. Only Class 2 is allowed a throttle, Was almost 100F yesterday so I rode my bafang middrive conversion so I wouldn't have to sweat. Now...

    ToSeven DM Series Mid Motors

    Seems like the odds of a working DM02, even purchased from a US seller is less than 50%. At least it was the peripheral stuff that didn't work, and you got them replaced quick, I don't mind rolling the dice on a DM02, but don't have a candidate bike, nor the room for it either, Maybe next year...

    Power Bank as Emergency Booster Battery? / Bath Mat for the Mental Fool

    P1 is the number of magnets in the motor times the gear ratio of a geared motor. It's used to calculate the speedometer reading on the KT displays. The max allowed by the display is 255. If you need a P1 greater than 255, like 300, then you set L2 = 1, and the P1 entry is doubled, Put in P1...

    hello everyone I'm new here and would like to learn some things..

    Did you buy this one? The intelligent learning works, and is a good feature if you know how to use it. First time you must power it up with the leads connected. If the wheel spins in right direction, disconnect the leads and you're done. If it doesn't spin or gos backward, repeat powerup til it...
