Giant CT 102 Urban Commuter Bike

In previous posts I spoke of converting my Giant CT 102 Urban Commuter Bike into a DIY LWB Mid Racer, Low Racer, or FWD Delta Trike.

An alternative might be the following DIY FWD Low Rider Conversions by Robert Horn, of Englewood, Colorado, USA.

Very few DIY bike designs are as ingenious as these F’Lowroller variants. They are remarkable for their economy of design, and deserve greater recognition and exposure than they have gotten.

They are clearly superior to many better known DIY bike designs that call for the fabrication of many components from scratch. They require only one donor bike, not two or even more. They ingeniously move the bottom bracket / chainstays / rear wheel to the front, and the front fork / front wheel to the rear. The original handlebars can be reused as well. Waste not, want not.

They are more aesthetically pleasing than many DIY bike designs, which often look very “ghetto.” The F’Lowroller variants look futuristic and elegant — almost like factory prototypes debuted at an industrial design expo by some big name bike manufacturer.

Giant CT 102 Urban Commuter Bike

In previous posts I spoke of converting my Giant CT 102 Urban Commuter Bike into either a DIY LWB (Long Wheelbase) Mid Racer or Low Racer

An alternative might be the following DIY Front Wheel Drive Delta Trikes.

These trikes are exceptionally easy to construct. Their front drive / rear steering configuration is simplicity itself. It obviates the need for either the complex steering geometry normally found on the front wheels of tadpole trikes, or the custom made hubs normally found on the rear wheels of Rear Wheel Drive Delta Trikes.

These ingenious ice trikes simply flip the rear triangle of a DF bike upside down. Presto! Instant FWD assembly for delta ice trike. Equally applicable to delta street trike, such as the ones shown above.

These are not quite as easy to build. Therefore I would probably not attempt to build them. But they are beautiful looking trikes well worth studying for their ingenious lean steer design.

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.
