Re: How to build a brake light?

My controller does not have a brake light output. The idea is to send a singnal 5v or 12v to back light when the brake is activated. Which component is better to use? A transistor like a switch? A relay? Maybe someone have a example of existing circuit? Brake signal wires don't have enough current ...

Re: How good is Cyclone 4kw coaxial suspension bike?

Hey guys I posted a review on the 3kw cyclone forum but I catually purchased the 4kw full bike and ended having a real bad experience! He bought the complete bike, which is no good. They should sell this as a frame kit only. For others interested, here is the post from the other thread I will reply...

Re: new cyclone 3000 w mid-drive kit?

These utilitarian boxes are actually more stealthy than triangle boxes in the frame, these ones look like you are just carrying a toolbox. I'm thinking of making the bike m...

Find someone smart who knows if the hardware is different or just the software. There is a way to trick these into taking higher voltages, but it is only safe if the hardware is the same.

Re: Neu 8057 6kW left hand drive hardtail with vesc and encoder

I'm thinking of something similar with the (I think inrunner) QS motor 2000w mid drive it has 120 stator diameter and 70 magnet height. It looks very high quality. Some guys use the 3000w motor in dirt bike conversions, it can take 15kw easy (11kg), so the 2000w(~7kg) should be good for 8kw minimum...

Ok, I have my board now, will solder it in a day or two. 2018-10-24 18.02.08.jpg Can I ask if you have blinking turn signal feature? I tried to look for blinking signals, they are not integrated, lights and big relays are sold separately. It should be able to be controlled with a micro controller.

Re: Bikee Bike final review

I think having a bluetooth dongle and the phone app is the way forward. If the bikee app and the controller are well designed, you should be able to make the throttle as smooth and curvy as you want, both for pas and throttle. So two motors should feel comparable with the same power, if you have the...

I ride mostly on the street and easily keeps up with traffic on roads with 35mph or less speed limits.

Re: Rieju 50cc conversion

Changed my mind, wanted to keep the available throttle band and since i had no issues for the high throttle i just added 470 Ohm to the low/ground side. That should raise the low voltage output to 0.4V Result is a decent amount of dead band, really good throttle response and no controller faults :D...

Re: GNG X1-pro 3000w

3000W is enough power to sustain 45mph, so let's be honest, this drive is ideal for building an off-road machine for fun, not for stealth. ( nobody cares about this where i live. I've seen motorcycles on trails before ) 3000w is certainly enough to sustain some high speeds, the real question is if ...

Re: My RC Mid Drive with Single Stage Reduction

Most of the higher rated ones have an open design, others have very low voltage ratings making them impractical for high powered ebike use. That vent seems to be the reason they are so small and light but high rated. Cyclones are closed. These RC motors are not made for bike applications at all. A g...

A guide with sections similar to the ones you made would make more sense than just forum posts. I have been thinking myself of making such a thing, but I only have the cyclone coaxial motor, so not as useful here.

Re: new cyclone 3000 w mid-drive kit?

That's easy:) So I got the replacement throttle hall sensor working. Had to use an Arduino to invert the signal, but it works alright. For whatever reason, the new sensor is very jittery, and makes the throttle jump around a bunch, so I implemented some mediocre filtering. Also, the controller is s...

Instead of working harder, you should work smarter and get a fairing or a speaker either in your helmet or on the top tube directed at your face.

Re: I ordered a new em3ev battery

Do NOT top it off every night! Keep it between 75% and 25% for usage and store at 50%.

Using it 100% to 50% is much worse than 75% to 25% while using the same capacity.
