Recumbent Bikes are not that common on the road, although they are growing in popularity. They are especially popular on GrabCAD as well. Maybe Engineers appreciate the higher safety, low-drag, ergonomics and unique mechanical engineering challenges of a Recumbent bike. So do we. Here are all of the best ones we found on GrabCAD.
This is the Lighting 03 by Yavor, featuring a "Linear pedaling system, electric drive, full suspension and center hub steering". If only he had the money, he'd be able to make one and see how it rides....
This is a Steintrikes Mungo Recumbent Bike, posted by Robert Stein. "Most of the work is mine, I "grabbed" the brake disc, the brake levers and the Shimano cassette from GrabCAD, some of the parts are already available here and I will select the frame parts and upload them separately for those who want to have an assembly file of this trike...".
This is simply remarkable - the CT Velo is a three-wheeled, two-seater recumbent. Designed by GrabCADr Stoycho, it can be folded in a number of different ways to suit the situation (or even style). Storing your bike has never been easier!
Alright, this isn't a model - but we thought it was cool that we're beginning to see more images of interesting Engineering and Design. This is 'Trike Recumbent' by GrabCAD Engineer Marcel Rouenhoff. Featuring a 1 kW motor, this bike hits 45 kph. It turns not by pivoting, but by tilt-action. "The smallest turn radius is 1 m. But then one should not exceed 6 km/h.... You can easily steer without hands by just turning your upper body to the left or right."
Care to travel along the highway. Well you may not ever have to be motorized. As it turns out, you can break some barriers via a bike. Here's a short video of the World speed record attempt by Bike over a flat surface. Canadian Sam Whittingham managed to reach 133 km/h (83 mph) in an aerodynamic recumbent bike.
