    Kuberg Free Rider

    Hey guys, Im trying to upgrade my rear tire on my Freerider. It is still running the stock 20 x 2.5 creepy crawler tires. I misread a previous comment stating that a Shinko Sr241 trails tire in size 16x3 would fit so I ordered one and it was way too big for the rim. Is there a smaller size...

    Slow acceleration for 72v 2000w ebike.

    Okay here it is. I installed new rear shock as well as front and rear tires. I freshened up the chain and applied chain oil.

    Slow acceleration for 72v 2000w ebike.

    The previous owner of the kuberg replaced the original shock 240mm to a 265mm shock and its causing the chain to rub on the rear arm. I am looking to get the original shock to fix the chain issue as well as lower the ride height as it sits the back is more raised than the front making the ride...

    Slow acceleration for 72v 2000w ebike.

    I got a deal $2500. Its a bit unkept I will need to look at adjusting the chain since it rubs on the frame a bit and the tires will need to be replaced soon. The battery looks to be in good condition I rode for several miles last night.

    Slow acceleration for 72v 2000w ebike.

    Quick update! :D I sold the bike and picked up a used Kuberg Freerider 48v 8kw. Dammn thing is like a bat outta hell! This thing is more to my liking it's lightweight and front wheel pops ups if your not careful. Now I just want to customize this freerider as far as height and suspension to make...

    Slow acceleration for 72v 2000w ebike.

    Okay so I requested a refund from the vendor. I can either return the bike to get my refund(I paid 2k for the bike). He can also refund 200 and I keep the bike. I am on the fence if i should return it or keep it and use the 200 to put towards controller or battery upgrades if needed. My other...

    Slow acceleration for 72v 2000w ebike.

    Hi guys, Thanks for the helpful input. I will do more research into the lithium battery specs and see if upgrading the controller amps will help. On the lcd it shows watts being pushed out is ~2600watts. I may just take the bike back to the vendor. I have come to the conclusion that it's...

    Help- 48v 20ah battery not balanced.

    I will do that thanks. I actually removed the battery from charging until my new charger gets in I don't trust the old one I have. I will definitely find a spot to charge safely for the moment the battery is in some thick plexi type enclosure.

    Help- 48v 20ah battery not balanced.

    Thank you e-beach. I think I may just leave it plugged in I read that balance charging is extremely slow but after a single night of charging I did noticed a small change in the cell voltages. Notice the first 3 cells are even now. If after about a week I don't see an improvement I will try to...

    Help- 48v 20ah battery not balanced.

    Here is some pictures of the setup it is a lithium ion battery. I am not sure how the wiring is setup under all the tape. It is in a hard box that came from the factory so it should have been protected from damage. I counted 9x13 cells wide for a total of 117 cells. People have suggested to...

    Hi all, I'm new to lithium battery technology. I bought a used V-Power 48v 20ah 13s lithium battery. The battery charger is going to green although the battery is only getting up to 48.9 Volts. I checked the 13 wires going into the bms and calculated the differences in volts. It looks like the...
