I recommend you never to buy an MKS ECOBIKE…the biggest scrap. My scooter has now 1.5 years and had to have the following new things: V-belts cheap approx.18€10×180,00 € V-belts medium 1×22,00 € V-belts expensive 1×26,00 € alternator 1×42,00 € V-belts front 1×50,00 € inspection 1×180,00 € spark plug 1×18,00 € counter-pressure spring 2×19,11 € clutch 1×37,00 € V-belts 1×12,40 € 586,51 € I did not buy the spare parts, not that you think I buy 11 V-belts. A mechanic has now found that the centrifugal force coupling was broken from the beginning and makes your V-belt melt and stink. The scooter is pure scrap. Some mechanic wanted to look at the nich and meant to us we would still have vvvvvvviiiiiieeel fun with the scooter. Look forward to your comments.
