Windone k2 urban explorer

Windone k2 urban explorer 500W motor 48V battery 32KMH-40KMH Price change due to me ordering a second battery and charger for the purpose of getting more range not because there is an issue with the one that’s currently with the bike I get about 35 kms with throttle only 40-45 pedal assist it’s not hooked up to be duel batteries in parallel yet I will be doin small mods and tinkering with it abit and the price will go up accordingly not the full price of the work and parts that will be put on but close to the battery and charger alone would cost u an extra 480 I’m not asking for that tho fun bike weather is getting nicer I’m looking to upgrade so this one gotta go great bike let me know if ya want it thanks
