    Cobra Go Kart

    Thank you Functional Artist, your assistance is much appreciated! What is the difference between the charger you Linked to, other than it being 2,5A whereas the one I Linked to was 5A? I think the battery has Aviation style connector. Also, do I understand you correct with «not being able to...

    Cobra Go Kart

    So, I found another one, 58Ah, 50A continous: China battery, 2000W Tempting... 58Ah and only 4 kg. It cost about the same as 4 SLA batteries with 12-15Ah. How about this charger? Ebay Charger On the small "Bugatti" car I mounted the charger onboard and connected it through the controller, I...

    Cobra Go Kart

    Batteries: I did a search on Ebay and there are a lot of these: Chinese Li-ion 58Ah: Seems too good to be true... This surprises me: "Maximum operating current: 13A" Is this correct? Seems very low, for 1800W I need 37,5A if I am correct. Compared to 600A from the battery pack Functional...

    Cobra Go Kart

    So, I have started thinking about batteries. I used 2 lead batteries in the small build, it worked very well so I thought about the same for this build. I see my local supplier has 18Ah batteries as the biggest. 4 of those will however be costly and heavy, 24kg! I can get a used/rebuilt 15Ah...

    Cobra Go Kart

    That is beautiful workmanship! I look forward to follow the progress. I had never heard about the Vale before, wonderful special. I remember seeing a homemade cyclecar in a private museum in England, it was built by a father to his son as a copy of his own racecar.

    Cobra Go Kart

    Ahh, that was the first mini car for my boys, it is a pedal car converted with a transaxle from a mobility scooter and a speed controller off Ebay. I have widened the track and fitted wheels from a pram. My youngest son has driven it for many many hours! I converted the electric "handbrake"...

    Cobra Go Kart

    This project have been at a standstill for loong, but now I have had some progress at last. I have come to the conclusion that I do not have time to do it like I really would like, so to get it finished I just need to put it together and get on with it. I had another thread on it but I get a...

    so slow and boring...

    I used a complete axle from a Mobility Scooter to power my sons Pedal Car. I think it is around 20:1 gear reduction. Something like this: https://www.ebay.com/itm/DRIVE-DAYS-ST1-TRANSPORTABLE-MOBILITY-SCOOTER-TRANSAXLE-FASCIA-WHEELS/183413530792?hash=item2ab44c60a8:g:S2oAAOSwbVdbjQLZ:rk:9:pf:0...

    Electric Go Kart

    I am sorry for my comment about overweight people driving Mobility Scooters. It was meant to give a humorous twist to the fact that these motors have to be designed to carry heavy people. The point about americans was because there is few of these here in Norway but they are more common in the US.

    Electric Go Kart

    My 4YO have a transaxle from a Mobility Scooter. I am not sure how many watts this motor is, it is adequate for him but not more (the vehicle is much lighter than yours though) The motor is absolutely massive for the power it has, I can not imagine it ever overheating. It was made to drag...

    Builder advice - Tony Kart with Shelby Cobra body shell

    Thank you, very tempting but very costly! These guys in Australia sells a cheaper kit: https://www.ebay.com/itm/Gokart-Quad-ATV-Buggy-Front-Stub-Wheel-Axle-Hub-Disc-Twin-Brake-System-/262895856941?hash=item3d35d06d2d I would then have to change to another type of stub axle AND find a rim with...

    Builder advice - Tony Kart with Shelby Cobra body shell

    Aha you say that the Axle will/could bend? I am Sorry I did not catch that when you said that the axle was "flimsy". My cart will be considerably narrower than the original cart. I also plan to weld a cage on Top of it to fit the GRP body, hopefully this will stiffen the body and minimise the...
