Hello dear forum, where my mother’s scooter (Kissbee 50 4Takt) has said goodbye to the V-belt (tore it off). Then I got a new similar and new Vario rollers. Unfortunately I didn’t know which weights are originally installed in the scooter (the old ones were very worn out), I decided for the 15×12 – 5.20g version. Now the scooter hardly pulls away on the mountain. That means the weights are too light? Can anyone tell me how heavy the original weights are? Mac Does it make sense to buy a voting set? Thank you very much Timo545
