MAKE magazine columnist and skilled inventor Saul Griffith is hard at work crafting effective eco-friendly alternatives to driving a car for errands within a 20-mile radius: cargo bikes with optimized steering geometry called Onya Cycles. The beefiest style they make can carry you plus 150 pounds of cargo at 20mph. Saul is pictured above in the Front-End Loader with his son Huxley, and his company is profiled, along with a handful of other cargo bike builders, in the newest issue of MAKE, Volume 24, on newsstands October 26. Check out this great little video by GigaOm’s Green Overdrive, and look for the article in Volume 25.
