Phil Bridge, 21, of Sheffield Hallam University, said the bike was strong enough for a rider weighing up to 12 stones and would not go soft in the rain, although it has a life expectancy
of only about six months.
The bike is made almost entirely from recyclable and recycled materials, using mechanical parts that can be reused. Mr Bridge said: “The lightweight quality of the cardboard,
combined with its low cost, means it’s possible to create a bargain bike that’s also less susceptible to thieves.”
