Sorry the pounds spelled out didn't register as a price inside my thick skull.

It's still available because you have no price listed, which is actually against the rules of the for sale section.

The middle setting of the switch is as if no switch is used. The other 2 positions short each of 2 wires to ground (the 3rd wire). How it actually plays out in use depends on how the controller is programmed for the 3 speeds. When ordering controllers, I always request that the default (position 2,...

The Nucular controllers have the best throttle response I've ever used. I use the option with a hybrid of torque and speed throttle, so you get torque of the amount the throttle position demands as long as the corresponding speed of that throttle position isn't exceeded. It measures actual phase cur...

The thing hurting costa rica is the no license requirement, not the no type approval or other bureaucracy. We have license+insurance requirement in a few EU countries (still no reg, no type approval) and the incident rates are very, very low. 12 years and I haven't seen another homebuilt that I was...

Fair enough. But your odds of getting killed in a traffic accident (on a population basis) are about five times greater in Costa Rica than in the UK . Pick yer poison.

The way I ride the odds are so close to zero that any stats you looked up don't apply no matter what vehicle I'm operating.

I wouldn't stop if they tried though, not letting some monkeys steal my stuff.

Can you get away with refusing to stop for police there?

John in CR

I'd never live there with those ridiculous laws written with the help of hard core cyclists. The law here is above 5000W electric motor output makes it a motorcycle, and under 5kw output makes it a moto-bici, that is legal to operate. No license, no registration, no inspection, no silly pedal requir...

I sent a request for pricing along with more detail dyno test info on their motors. I hate when companies hide their prices. It's one thing if they sell only wholesale and don't want to undermine their distributors, but quite another when they're embarrassed to show their high price.

It turns out that current with the brake on is a show stopper for my idea. Current draw with the controller on is a tiny 20mA, which is great, less than 1/8th of what I've seen with any controllers with the power potential of the Nuc 12F, however, with the ebrake applied (I use a throttle for the va...

This bike is being set up to run without a display (at least for now, because I don't want my son changing settings until he gets plenty of miles under his belt), and on/off seemed a bit conflicted using a switch on K1 to gnd while using the display to change settings while disable was set up as "sw...

How heavy is the vespa in that wheel-less motorless state? I worry that you've got a pretty big weight handicap to start.

Of course go for the big motor, and put plenty of battery. You want the result to kick the crap out of any other Vespa.

Did you manage to get the version with the solid gold connector bars?

? At $500/module that's $12,000 for a used Nissan Leaf battery.

Someone along the line seems a bit too greedy in this salvage supply line.

John in CR

What are you guys using for on/off switching to get absolute reliability? At least with my setup, a switch on K1 to ground doesn't always turn the bike off, often requiring a 2nd cycle of the switch. I'm not going the contactor route...too expensive and bulky and introduces new failure points. I use...

Pole pair default is 23, you should input it manually lol

Ah, that makes sense now, since so many hubmotors have that pole count. This just happened to be a motor for my son's bike, not the 10 pole pair hubmotors I use mostly.

I couldn't find this issue and fix mentioned anywhere, but during my first setup controller setting changes would not stick even though during save it reported the save was successful. While going thru setup in the motor section (even without using auto setup), the motor started spinning, so be sure...

"Slumming" is definitely the right description. Other than nearly freel SLA to use as doorstops or for a conservatively run home pack for wind or solar, someone would have to pay me a lot of money to use SLA batts again. I don't even use them for car starter batteries anymore.

Come on guys. 2 inline wheels on fixed parallel axles won't turn. Period. With 2 wheels the tires will scrub a bit due to the different circumferences in contact with the ground, but it will still move in a straight line. The skateboard above with 7 wheels on each arched axle is a perfect example of...

That's an awesome price, not much less that I'm purchased nearly new used and perfectly good lithium batteries. Hopefully that kind of recycling price makes its way down here.

John in CR

It looks used enough to graduate to a more efficient more quiet brushless motor setup.

John in CR

Any comparison of that silliness to the fastest most powerful ebikes on the forum is quite an insult.

To me urban environment means short distances. Now that I live much closer and don't have the 60km/day commute, none of my bikes require daily charging even if used exclusively. Removable batteries don't even cross my mind. Can't you charge at home or at work with batteries securely mounted on the b...

John in CR

You'll need a lot of offset to use such a slack head tube angle in the first pic. Otherwise it will have very sluggish steering and you won't be able to keep it in a straight line at low speed.

John in CR

Okay so I'm having a debate with my friend whether a design like this would work, he seems to think it won't turn and Im saying it should ride great. If you lean that thing over, it will turn. How sharply it will turn is a function of wheelbase length and the qualities of the tires. Bikes turn by c...
