    Snow moped

    now, thanks, it got a little better anyway. but It's probably too small to be funny enough. Now it also shut down, error code 1.Motor hall Error. I have to take the hub motor apart now I suspect?

    Snow moped

    Not much else has happened with this one, but now there was some snow in Stockholm so I wanted to try again. I bought myself a FARDRIVER ND72360 Controller. to be able to force feed the little engine a little more. First, the phase cables melted :eek:, so I changed them to a bit thicker ones and...

    Skil 20v batteries D terminal?

    No maybe not, some universal from amazon for Electric skateboards it says, the gearing will be good

    Skil 20v batteries D terminal?

    If it is to any help in guess work the middle one goes to the yellow here in the charger when I took a sneak peek. By the way this is the mini project I hope they can supply power to. A large/small drone motor in a gearbox driving the discbrake similar to Bimotal if you have seen that :D

    Skil 20v batteries D terminal?

    Hi! I had some luck and won some Skil tools and batteries. Now when I have several good batteries I would also like to use them for a new small ev project too :D power a RC-motor. I plan to 3d print a holder and will there have +/- terminals that slides into those slots in the battery. Now when...

    Old Husky conversion

    Hi! I can show some pictures of my boat motor I did a vile ago. My dad found this old beauty in the metal trash. I measured little on the golden motor I have on my old YZ80 dirt bike, should just fit under the hood, So I ordered another in 48V version, and it did fit :bigthumb: Was so...

    Snow moped

    thank you so much for your detailed answer! :bigthumb: That sounds logical. I will now first wait for snow and test drive a bit as it is now, probably I will want a little more power so it will surely land in that I change controller and then it will surely be one with a separate throttle...

    Snow moped

    Another question for you, what do you think about tweaking a motor like this with a little more amperes? Since I already had a 48v battery, (with100A BMS) I chose the so-called "2000w kit", but the same motor seems to be sold in 3500w version, when you give it 72volts. How would it work instead...

    Snow moped

    Yes seems quite complex, Maybe I could keep that unit inside my Swingarm box and just run a 3 pin throttle to the handlebar. (Real snow bikes usually have a spare fuel there, so I thought it would be a good idea to place some stuff in a box there now as well.) Oh by the way, the bike got soo...

    Snow moped

    This was the kit: https://www.aliexpress.com/item/1005003652843765.html?spm=a2g0o.9042311.0.0.714f4c4dEMoHxH This was the new throttle I have swapped grip on now, doesn't say much: https://www.amazon.se/gp/product/B0946TJWK5/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 Don't care about...

    Snow moped

    The engine kit comes from some pretty mad off-road scooter, probably a little too small for this snowmobile, but the ambition is not a mountain goat, but rather to pull the kids' sled a few laps on a nearby football field. It was a complete kit with this throttle and controller etc., it is...

    Snow moped

    Thanks, I need some help now, cant figure it out with the throttle. The kit I bought came with some kind of finger throttle that I don't want to use, I want to use a twist throttle (that I managed to put a nicer dirt bike grip on to) The problem is that the old one that fit had six wires. Goes...

    Snow moped

    I bought a replacement track and drive wheel from a snow blower at the local hard ware store. I figured out a bolt on unit that should fit inside the original swingarm. Ordered some laser cut steel and welded/screwed it together. The other wheels inside are 120mm kick bike wheels. Took out the...

    Snow moped

    Just started a small new project before the Christmas holidays. It will be a small snow moped. Got so inspired when I stumbled across Moonbikes 😍on the internet. (google it, a light snow vehicle with hub drive) Then I just found a empty dirt bike frame cheaply on an ad, a 2013 KTM 85. No wheels...

    Vintage Electric MX (YZ80)

    One year later, still happy, bike work great :bigthumb: Still I wanted to improve the gearing, could not find any smaler front sprocket for the 20mm axle and 428 chain. So I made my own 20mm keyway sprocket. On the rear i have been using a 55 tooth this summer. It top speed is 70km/h...

    Vintage Electric MX (YZ80)

    Now I have had time to drive a little more, everything works great. Topspeed is 70km/h, I think that is enough for forest riding. But I would like to have it slightely more agressive from zero, The power seems to be there but comes after a short "ketchup effect".. Any advice on what to adjust...

    Vintage Electric MX (YZ80)

    Thank you for the links Fechter, I saw there were copies of Ktrak on Alibaba now, would maybe be a good start to modify. But I could easily fit a 100 mm wide track, I assume they are only about half that if they are supposed to fit a normal bicycle.

    Vintage Electric MX (YZ80)

    Anyone with thoughts/help about optimizing the settings?? In the mean time I made a ramp so I can bring it easy on the hook in the back of the car. Also I have changed the gearing now I run 11front sproket och 54 rear. Also changed the brakes and bearings when I had it apart. Also the...
