If your into night riding, then The Zulu Glow in the dark bike ($399) is just what the doctor ordered. The Zulu’s paint is solar activated. Just put your bike in the sun for an hour and you are good to go for about an hour at night. The Zulu can be ridden as either a fixed gear or single gear bike by flipping the rear hub. The pedals of a fixed gear bike rotate with the wheels. Applying backwards pressures on the pedals acts as a break. When riding in single gear mode you can coast with the pedals stationary. The bike comes fully assembled and arrives in 5-7 business days.
