If you're converting your bike to electric using one of our conversion kits (BBS, Samsung Street, Samsung Off-road or 1,500W) this brake set is a great option if you're concerned about stopping power. The Tektro Dorado E710 hydraulic disk brake set includes front and rear 180mm disks, front and rear complete levers, lines and calipers (already bled and ready to mount) and DO.4.0 adapters for iso standard mounts. 180mm brakes give you added mechanical advantage over standard 160mm disks. 203mm are the next size up but they are notoriously impossible to adapt to regular bikes. That makes 180mm the perfect size for your conversion. If your bike has PM forks, you can purchase a separate D04.0 adapter separately.
