Re: Chalo's cargo bike with BBS02

That's cool. I like the small front wheel under the cargo, just like a smaller rear wheel on other cargo bikes. Gets that big load low to ride a bit nicer.

Hoping to get back to welding up weird frames soon, but nothing really planned yet. Might take some of your bike and put it into the next one.

Re: Snapped fork dropouts

With the alloy mainiou fork, you need two good torque arms. Get the one from Grin, that has adaptations to better fit a shock fork. You also, absolutely must have two c washers between the fork and the TA, or some other type of small washer that fits the dropout cup. Just tightening the nut without ...

Re: Back Wheel Motor vs Front

Traction is the big reason to go rear, especially if you ride any dirt, even just a short driveway gets tricky with front hubs. But if you are good enough a rider, you can of course ride anything, anywhere, anytime. Major reasons to go front are trikes that can only use a front hub( or mid drive of ...

Re: Do batteries "waste away" if not used?

Yes, your shit should last a lot longer than a typical e bike battery, that is 5-10 ah too small to begin with. From day one, a 20 amps controller is beating those small bike batteries into shit. By the third year, lucky if they have half capacity left. Same to some extent with the HK lipos, they ju...

Yeah, anything could be used between the frame and the epoxy to make it stick to the mount, but not the frame. Piece of paper, tin foil, plastic wrap, etc.

Re: Araldite as filler between frame and bracket?

Rubber strips can fill that gap. Like cut up thorn resistant inner tube.

Much thinner than 2mm. Quite possibly thinner than 1mm, depending on the quality of the frame.

Most likely your charger is set to lilo, which gives you a 4v charge. Those things are real fun to figure out how to use, to program them to the type battery you want.

I don't know the case, and can't see enough to dope it out in the pictures myself. On the bms connection, that looks right to me for the main wires. But to make the bms work you have to connect each cell group to the bms using that long row of terminals, using female plugs that match what you have o...

Re: Rescue Motor - Aotema (Wilderness Energy BD-36)

No, they suck for climbing hills at low speed in 26" wheel, the BL much better. The culprit is the extra heat caused by the brushes, and once you toast a set of brushes, then the motor really melts itself down. The motor is wound fast, comparable to a 6 turn 9 continent, making it too low rpm on gra...

True enough here too. The sand I'm talking about comes straight from granite peaks 9000 ft tall, about 4 miles from my house. Its like sandpaper grit, so you either flush it out regular, or you can just go dry. On the street bikes, its not so bad that you can't water flush, then lube with white ligh...

Depends on what you call high power. For 3000w on up, I recommend something like this. This is what I had for racing. Pinch dropout, on Race bike..jpg Or in any case, for motorcycle like power, you need to have something designed to hold more than 1 hp, usually a custom rig of some kind, torque plat...

Re: Question about hobby charger amperage fluctuation

I'm still betting on he's got the thing set to lilo, and its working exactly as you'd expect. At some point just short of 4v per cell, its stopping and going into balancing to 4v mode. Taking forever, if they are not very balanced. If the cells are not brand new, then whatever the RC charger balance...

Re: Lipo with BMS or RC Charger?

How often do you beat that battery so hard it needs to balance? Every cycle? If so, then you need a better RC charger, but it does not absolutely have to be the very best. Just something in the 150-200w ballpark will do. Balancing will still take forever, but at least the fill up to 4v gets twice as...

Re: ? Gross Brake = 3000w Brushless Hub motor

48v running a 22 amps controller should be about the max legal in CA, as the faster e bike. No throttle allowed. This is how Don Costansa had that law written. So a typical 7 turn hub motor on 22 amps would qualify ( meaning a pedego e bike), and go 27 mph max.

IMO, hand fitting shit is what custom is all about. If you plan to use stock stuff, same typical rim width as mtb's and cruisers, then of course no need to hand fit anything, just make it same as you measure down at Walmart.

Re: Freewheel Maintenance

I can see them grinding to dust if you don't flush the sand out often enough though. That's why I pour oil through them on the dirt bikes, messy as that is.

Far from proper bike maintenance, but on the dirt bikes that rarely pedal, and use cheap freewheels, it works for me.
