    Disappointed in the Bafang BBSHD Mid-Drive Conversion

    We used to talk in hushed tones around the campfire when speaking of the big Bafang. The curse of the locked down controller has claimed another legendary motor,

    Marginal utility. One tenth the price of a Vado with sales tax. Nine tenths of the functionality. Zero percent of the snobbery, but priceless for satisfaction, .

    Safety Wiring { Maybe not a great title ? }

    I've added tail lights and headlights to my daily riders. They use rechargeable cells and recharge via USB so I've run power cables front and rear. and they charge while riding, I've had prissy riders tell me that the strobe mode on my front light is too bright. Good! I try to keep it pointed...

    Upgraded to lithium issue

    Looks like you have an older ebike that used lead acid batteries, and you bought a 36V 10AH battery in a green shrinkwrap from amazon? It shuts off under high current, buit works on lower power. The amazon ad's smallest battery is 36V12Ah with a max current of 15A. It can probably do a bit...

    Show us pictures of where you ride your ebikes!

    Last Sunday was Bike The Drive where Chicago blocks off cars from Lake Shore Drive, and thousands of bikers ride with the City on the west and Lake Michigan on the east. I had expected more ebikes, but my guess is about 5% at most were riding them.

    Crazy Walmart mid drive deal $349

    I'm not in a select location, too far from the warehouse.. Everytime I look, the $349 grey bike is out of stock. The white one has dropped in price from $699 to $549. Still too high.

    What camera do you use if you are into photography, when cycling

    Had a tire blow out at 6:46 AM on I-90 in West side of Chicago. Pulled off into a sketchy part of town. Hadn't changed a tire in 15 years, but I changed this one n 15 minutes and we scrammed. Turned out to be a great day for a ride.

    What camera do you use if you are into photography, when cycling

    I'm going on a ride tomorrow on a pavement ride thru CHicago with maybe 8000 other cyclists. My last time with this event was before Covid, and while I brought my m43 mirrorless, I didn't bring any SD cards, so all I had was a $40 Akaso video camera. Worked well enough, Taking my Olympus OM5...

    Raleigh Array issue....🤔

    It turns on the first time you install the battery, Then it can't turn on until you re-install the battery. This is with a full charged battery too? If it's almost discharged or weak. this kind of stuff is more likely, To be clear, is there a handlebar display or handlebar switch that you are...

    I need help!!!

    A box of junk controllers looks like this. You cannot tell much from the label. You have to look at the connectors. You need the wire diagram that is in the seller's listing, And they are all different. It's not worth the time to guess on every connection. You're on your own w/o any more...

    DIY build my own E-bike battery - tips?

    Looks like a 4S-4P. Should hit 16.8V if the cells were good, Stuck at 13V. You might have all four groups at 3.5V, or more likely, some at 4V and the others at 2V, ANyway, for the time being, neither the car charger or the bench supply can force enough current to go much higher. No worries. If...

    I need a carry bag for a foldable ebike

    My Schwinn Loop came with a carry bag, but those are narrow 20", and that's a 33 pound bike before I added a 6 lb motor, A 20" fat tire bike comes in around 60 lbs or more, A bag would rip when you lifted it,

    DIY build my own E-bike battery - tips?

    There is a test standard that says a cell must not start a fire if you short circuit it. Quality cells have pressure sensitive circuit breakers inside that are intended to break the circuit. They also have vents that blow if the pressure gets too high. The same standard says you can overcharge a...

    DIY build my own E-bike battery - tips?

    FYI. He needs insulating washers over the positive terminals. It's for reliability over time, and also good insurance if your weld is done off center. There's a real chance one could put the weld tips down off center and short the positive terminal to the side of the cell. I probably would have...

    DIY build my own E-bike battery - tips?

    Samsung 50S, a 5AH 21700 rated for 25A if you can keep it cool. Otherwise, should push 10A easy and if you had a 14x4 array, that's a 52V20AH battery capable of 40A. Make it 14x5 for a 25Ah battery, In any case, go with a 5AH cell that's rated for at least 14A of continuous current. You will...

    I am lucky in that every time I check the link, it's out of stock. Would have bought one to go with our other six bikes, and I believe the dog has a couple to pull her trailer.

    First Build Direction; Test Motor Voltage, Safety Logic

    Gromike has steel forks on his front drive bike, as I do on mine. Alloy forks are brittle and likely to snap at the slots where steel bends. Some forks, even if steel, are too delicate for a motor. People use torque arms. which you can buy. The dropout slots are 10mm wide and sized for a 10 mm...

    First Build Direction; Test Motor Voltage, Safety Logic

    Most 48V controllers will run on 52V, but the low voltage safety will be set for 40V, about 3 V too low for the 52V battery, This is not a big thing, as the battery has its own low voltage alarm set around 43V. Since it's a front hub, you have to be knowledgeable when you want to go for higher...

    What a Difference Four Years Make

    When we were in Florida in January of 2018 and 2019, we didn't see but one or two ebikes on the popular paved bike trails. Now I imagine there are plenty of ebikes. 2019 was the last year we did the Bike-the-Drive thing where Chicago closes off Lake Shore Drive and lets 8-10K bikers do a 30 mile...
