The black lightning is built by high-powered cycles in California, featuring the thunderbolt, 4000 W motor. It has enough power to climb almost anything. It has a springer seat post and padded seat for great comfort. Braking is do by Magura four pistons hydraulic calipers for with with 203 cm rotors and a three speed control switch which allows you to tame acceleration. The bike weighs 60 pounds and has a large frame. I paid $5838 custom built and I average around 30 miles per charge. It’s a great bike in excellent condition, so if you’re interested, please give me a call for a test drive.
