Re: The Student-Made Industrial-Strength Electric Tricycle

Very interesting project to do with kids at school. Let's hope that some other schools copy your idea. This will be a simple setup, as you already have a convenient place to install the battery on the tricycle. Don't worry about the wheel, it is not the best MTB rim but still, those double wall alum...

Re: 12v battery charges in 2 minutes with 2 amp charger

I am far from being an expert in that matter, but here is my logic: When you add a 3rd battery that is discharged with the 2 other that are fully charged, it does not only draw power from your charger, but also a lot of it from the other 2. Then, the time involved depends also on the voltage of the ...

Re: Non rechargeable battery electric bike

More seriously, I think this might happen some day. Imagine a revolutionary battery chemistry that would last for 100,000Km or more, cars and other EV could be sold with long term energy supply included. There is so much yet to be invented in that domain. Could use a nuclear battery :shock: On a bi...

Re: Ae-line 1st build

I will try to run the 5304 with a 24 4110 controller on the Ae-Line at 100v 100A. Maybe I will find it a good combination of speed and torque. The Specialized will have the 5306 with the 18 4115, to try and see how it behaves. For today, I'm back to the mechanic, cause my torque arm and dropouts sta...

Re: Ae-line 1st build

If I understand well, what you are saying is that feeding more voltage to a 5306 will make it less efficient at lower speed. Then, to be able to ride it slow and keep it from overheating, I would have to give up on top speed. Your solution is interesting then, building a dual voltage setup might do ...

Re: Ae-line 1st build

Thanks John, It is especially for rough climbing at low speed, that the 5304 does not suit my needs. Of course I want speed and the 5304 is great for that matter, and it climbs not so bad when I can attack the hill at higher speed. The problem is that it loses efficiency and heats alot when the trai...

Re: Ae-line 1st build

I would not bother the noise, if I'd be riding in the mountain alone. In town, I want to avoid too much attention. My ride is not legal and the police might very well get me out of the road.

Re: Can't choose a good controller for Crystalyte 5304

Yep, I have the bigger version of this one (72v 49A), that I run with 18s lipo. I bought it from Maxwell65 and it has 18 4110 mosfets, so it is upgrade ready for higher voltage. The small one is not so ready to ugrade, but will offer close performance at 72v. They are not programmable, and their LVC...

Re: Ae-line 1st build

Thanks Well, the 18 4115 controller I bought from Lyen is rated for 150v 50A max. Right now, it is programmed for 100v 50A and I will install it on the bike next weekend. It should be pretty fast, and with a bit more torque too. Then, I know that I will not find it a good climber until I receive the...

Re: Can't choose a good controller for Crystalyte 5304

You can use the 72v Clyte controller, it will give more speed that you want with a 5304, and will LV shut off at 56v. Perfect for a 18s lipo battery.

I went in the mountain for a ride in the snow this morning. I was having a lot of fun with it, until the motor started to have hesitations and growling on accelerations.

Nice bike, and very light frame. I was also preoccupied with the weight, at first. Then, I realized that performance and range are directly weight dependant: If you want power and range, you will be putting a lot of weight, and you lite XC will likely end up around 80 pounds when you are satisfied w...
