My chain is loose which is causing it to jump whenever I ride the bike, which makes a clinging sound. I tried using a wrench, but it doesn’t tighten the axle nuts. WESLO pursuit E 25 model. www.weslo.com
Help someone!!!

contact the mfg or retailer for warranty or repair.
Most wheel axle nuts require a 15 mm socket or box wrench.
You need the right size wrench.
