Ive had a kuberg freerider for a good while now I got it second hand rebuilt it soon as I got it and now it's due again so here's a build thread if the mods I got planned for the old girl.
Stock the bike comes with a trails 14-3.00 rear tyre on 10t/80t sprockets with a custom 7 bolt pattern on the rear hub, that's limiting me to using the stock rear sprocket unless I change the hub, I've done some measurements and the rear dropout is 128mm with a 14mm axle on a 36h hub.
Oset 16 racing uses the same 128mm 36h hub but with a 6 bolt pattern that fits an oset sprocket carrier so 219 go kart sprockets can be used they also make a 9 tooth front sprocket so I can drop my head to 9-1 and change my top speed from 34mph to 30mph bit increase torque at the rear wheel not that it's needed but I drive off-road alot below top speed so a bump in torque and range is a blessing and i can always swap to a tarmac set up if needed.
The chain is long and expensive so I've got a 219 kart chain splitter and ill be making my own, the first chain is costing me more but over time I'll save money joining them myself and ill have the option of trying out o ring chains in the future.
The brakes on the bike are decent but stopping faster is just as important and going quicker when the road is ruff, the stock 2 pots and 203 rotors stop the bike well but 220mm magura mdr p rotor front and back with shimano saint 4pots will stop the bike better and give me some decent modulation when the going gets tough.
The stock charger on the bike failed few month back so I looked about and found chargery I got a c10325 24s 1500w version that gives me room to charge in as little as 40 mins in the future
Only thing I don't like about the charger is the charge connector with its lead and grommet over time that looks like a weak spot so I ordered panel mount anderson connector to mod the chargers front panel ill show a few pics and bit more detail when I get time to fit them.
I also got a front shock rebuild kit and got fluid on the way the shock still feels lovely to use but it's wise to give it a rebuild keep it fresh, as I get stuff done I'll post some more details my plan is to push the power on the bike up in the future but as to what way I go I'm unsure yet there's a 14kw controller available but I want to look inside the stock battery first see what cell holders it uses as to if I can increase it's cell count in the same foot print as to what to what final voltage I use, but any questions or what ever feel free to ask away.
