@banjaxxed So more darkside? Or less darkside. Lol

I will say Jen’s helical setup(I still haven’t posted a video but I’ve run the drive) is quite a bit more tame, mostly with the backlash chatter, which aids in it’s silence.

Try and stay in the light :rofl: I’m saying in comparisson to non-helical Jenso drives.

No extra charge AFAIK. This must be why you got black superflys even if you didn’t realise at the time

So I’ve taken it over some of the bigger transition bridges close to my house with absolutely no issues.

The Lowest point of the drive box before the wheel is 38mm. 2mm less then how my belts were setup. So no real loss there.

Something interesting I have noticed between different builds is the closer to the kingpin your mounts are the more likely they are to get hit. At least from what I’ve seen. Where wheel pulleys are less likely to get hit because they’re tucked up by the wheel. Idk I could be wrong. The point I was getting to is. The drive system basically resides where my pulleys we’re, so I think the chances of striking are actually pretty low…

Here it is clearing my big ass garage hump.

So even 25mm belts have no chance regarding power transfer?

@LukePL As far is instantaneous torque. Nope. There’s always gonna be the delay from the belt tensioning when going from coasting to under acceleration or braking, as the side of tension depends on the action performed.

The backlash on these gears so small(less than .15mm or 0.075mm per side of tooth) and gears do not shift the side of tension, just the side of tooth.

To give an example of this. Roll your board backwards so the road side of the belt is tight. Put a mark on the ground where the center of the axle is. Slowly roll your board forward until the sky side of belt is tight. On my belt drive system this is about 9-10cm of roll distance. On the gear drive to move from one side of tooth engagement to the other is less then 0.5cm of roll.

So while technically the torque “should” be the same end result in ftlbs. It’s more so about the delay of transfer.

Riding for me isn’t constant, I’m always on and off the throttle. I guess the only way to explain it, sometimes when im riding and I start braking I pull back super slow at first, because if you switch the side of tension to fast with a belt, it almost has the tendency of “bucking” or bouncing. So you brake wait for delay, feel engagement then pull back strong.

With gears there’s no delay or bounce/belt bucking.

Thanks bro for all explanation! Now I kind of get it :wink:

Have you done a speed/range test? How are you liking it so far?

Speed, it preforms the same as by loose belt setup, except with the confidence of instant torque.

Range… Unfortunately not as it’s been raining.

I barely got that ride in the hour break in rain the past week.

I miss the nc rains. I lived in Charlotte for 10 and Boone for 10 years, it would rain so hard they would close the school (asu). 52.65 freedom units of precipitation per year.

All the rain is doing is making me finish my e-surf for the lake quicker… lol

Blah rain.

Yeah man lol. I came from surfing. So only makes sense to circle back to it.

Those things burn up alot, off topic but anyway. Are you documenting the project somewhere?

Not yet. I need more parts to come in.

@b264 told me about the efoil.builders forum so I might document it there. But I’m not building a efoil. Just a murderous jetski type surfboard lol. Efoils don’t interest me.
