Bicicleta elétrica ridstar q20pro, 2000w, 52v, 40ah, à prova d'água, poderoso motor duplo 20*4.0, pneu largo para bicicleta elétrica de montanha para adultos

I am in love with this bike, lots of power, but the rear shock is way too stiff so I replaced it with a 500lb one, the gearing is too low for higher speeds so it can't be used as a speed pedelec, I'm thinking of replacing the front sprocket with a bigger one, but those are personal adjustments that I prefer, like I said, I love this bike, but that stopped right after I tried to fix insurance for the bike, apparently I can not get insurance without a COC document, which it DID NOT come with, now I'm stuck with an illegal bike which I can not use in Belgium, it cost me a lot of money and I can say it is worth it if I could ride it legally, I'm heartbroken by this purchase, let this be a lesson to anyone in Europe trying to buy this, just DON'T

Such an expensive bike and then scratched and damaged and the seat is so uncomfortable on long journeys
