Electric CycleKart?
« on: 18 May 20, 05:32 pm »
I was wondering if anyone has made electric cyclekarts? I know that there a few that have but I was interested to know of the running gear used etc? and if this is a practical idea. Thank you.

I am building an electric cyclekart but the powertrain is not built yet. The motor we are looking at and are probably going to use is a Golden Motors 3kW DC motor

I spoke to a chap at 4qd a couple of years ago for an electric trike I built and he was very knowledgeable on these matters. Just a thought.
If you can drive round corners, you're not going fast enough.

Doug Varey in the US has an electric Austin CK.   He has kindly shared some of his experiences and said its OK to pass this on.  So, here's a summary of the system he uses:

Quote
Golden Motor 3KW  (5KW was just more. More power than I needed. More weight and more battery consumption)
Controller Golden Motors 200A sine wave controller
Batteries  ALLCELL 48V 23AH (with integrated BMS)
10:72 #41 chain, this gives a top speed of 70~75KPH (which is where I start to get uncomfortable - there may be a little more there…)
Regenerative braking - YES
Total weight 275lbs (incl batteries)

Generally happy. Still need to fiddle with the controller settings. I am often frustrated by the GM program used to change the settings. To call it rudimentary would be flattering.

So far, I haven’t had the opportunity to race to zero. At Tieton this summer we drove several miles on roads out to and back from our event in the orchard. That plus running the timed laps did not take as much out of the battery as I expected. I had taken a second battery out (15AH from Morgan) to swap out for return trip but it ended up leaving in one of the support vans before I did. No problem making it back to town.

Doug is currently building his 5th electric one. Lockdown has given him the time to fill!
We must avoid torturing our brains with false problems, it occupies but it can annoy. In jest!

Unsure how to add a link without a massive ream of text but I noted there are 3kw brushless (low voltage 3 phase) motor and controller kits on Ali Express for circa £130 that might serve as a budget entry into electric propulsion, coupled to 2 parallel banks of 4 18v drill batteries in series would give a 72V battery of 10AH if using 8 5ah aftermarket jobs, even old laptop batteries use the same 18650 cells I've noted.
