Bicycles get around by pedals, chains, gears, and wheels. Except, all the times that they don't, and they get around by being carried by their rider. Anyone who spends significant time on a bicycle can attest— on nearly every ride, there's a time when your bike gets lifted off the ground. Taking it inside and out, going up stairs, placing on rear or roof car racks, hanging it from hooks or storage, taking it onto public transit, placing it in a workstand for adjustments...you get the picture.
For those occasions, I'm digging this DIY lifter handle, which makes carrying a bike as simple as holding a brief case.
Maker Mrballeng created the handle from a simple piece of soft aluminum (available at any home center) and a length of paracord tied in a "Chinese button knot."
