Giant CT 102 Urban Commuter Bike
In a previous post I spoke of converting my Giant CT 102 Urban Commuter Bike into a DIY LWB (Long Wheelbase) Mid Racer.
An alternative might be the following DIY LWB Low Racers.
These LWB low racers are constructed with a single length of straight tubing. A number of builders have used 1.5" x 1.5" x 0.125" (3.8cm x 3.8cm x 0.3cm) square steel tubing. This single section of mild steel tubing connects the bottom bracket to the rear triangle, and forms the main chassis of the bike. Relatively little fabrication and welding is required.
On a LWB Low Racer the cyclist is seated very low to the ground, almost as low as on a tadpole trike. The low seating height minimizes injuries in the event of a spill.
