Re: Lowrider eBike project

I was surprised how hard it was to bend back so there is still quite a bit of strength there I recon and now I haven't got the brake pressure on it it should be ok but if not I can just get a new one. The bend is to far up to be able to cut it and still make the adjustment holes, we will see how it...

Re: Bike build, what would you do!

A slow wind rear hub motor may be the best you can do since mid drive looks like it won't work. Here's a 12T MAC motor simulated with a 48V 14Ah battery, and 20A controller. Looks like as long as you don't have real long sustained climbs, it may meet your needs. Looks like it can handle 16 minutes @...

Re: Lowrider eBike project

Yeah if it goes now it will be the frame bending so lets hope that doesn't happen :lol: Have bent the sissy bar back and will give that a go and picked up a second hand straight rotor today. So it didn’t break when you bent it back? Is it strong enough? I was thinking that since you still have a co...

Re: Bike build, what would you do!

I see the quandary. A hub motor may be your only option, absent some major fabrication. How fast does the bike need to be?

Re: Regen

How did you get back up to the top of the hill? I'm thing of regen vs. no regen on a 10 mile ride I guess. How much effect the regen will have on a battery after a 10 mile run, vs. no regen. I have little doubt your down hill run was able to do as claimed. The reality is though, you can't just figu...

Re: Regen

That may be, but the amount actually making it back in to the battery is negligible. May depend on terrain. I repeated some tests on a hill by my house. 1 mile descent, 700ft drop, 15-17% grade for the steeper sections; 1v-1.5V increase in pack voltage after letting the battery settle (2V immediate...

Re: Regen

Speaking from my own experience, the average hub drive using an average controller, will be hard pressed to provide 5% let alone 10. I've noticed that the higher regen is set to (better braking), the less power goes to the battery, since it ends up stopping the bike before much is produced. The low...

Is it possible and if so to make it produce good amounts of Regen current back into the cells while it isn't under throttle? Any suggestions would help me achieve my final goal.

Re: hall throttle for CA v3.1 aux input?

The Presets mode works using up to three voltage levels, using a voltage divider on a three position switch. So you can use any voltage that's within the input range of the port, whether that's a continous sweeping range, or a stepped voltage, or several discrete voltages. It can even be used for t...

I had one of those. They were straight butted steel tubes, so the triangle is big, or bigger, depending on the frame size. I'd say this is a 17"/medium frame:

Re: hall throttle for CA v3.1 aux input?

If you wanted (and have the designer skillz) you could even make it automatic, with a high resistance voltage divider from the CA's power input to ground, to "scale" the battery voltage to a lower voltage. OK, now you're talking. Maybe another application of the automatic feature would be to introd...

Re: Max comfortable width of pack mounted in triangle

I about to be building a new battery pack and it’s going to be a 20S10P pack mounted in the triangle of my 1999 rockhopper. Because of the number of cells and the shape of my triangle and to give me good options for keeping current flow healthy I think I’m going to need to orient the cells 5 across...

Re: hall throttle for CA v3.1 aux input?

NOw, that said, If you set up the cadence PAS correctly for your stuff, you don't really need levels for the assist, because it's not just on/off like generic setups are--it's proportional, just like the throttle, because it's controlling how much throttle the controller actually gets. I'm going to...

Looks like a HiGo 9 pin connector (Z910). The more modern version that Grin switched over to, is the HiGo L10:

OK, so an 'oversized' battery is the way to go. But defining 'size' is where I'm still a bit confused.

Always buy more battery than you think you need, that way when you realize you need it, you have it.

hall throttle for CA v3.1 aux input?

I've harvested parts from my last thumb throttle purchase, since it wasn't going to work out for me. I used the switch and voltmeter, replacing the parts from my half twist throttle, and threw the rest of the parts in my parts bin. Last night I was researching the aux inputs on my cycle analyst, but...
