A: Actually, for experienced cyclists, it is easier than riding a regular bicycle if you follow two simple rules:

1. Communicate - decide in advance how to navigate around obstacles.

2. Lean into turns - don’t steer like a car.

The Velo-city 2025 video clip captures experienced cyclists enjoying their first ride on the side-by-side flexible twin bicycles after a safety briefing.

Please consult the SAFETY tab for essential bicycle safety guidelines and best practices.

A: Like single bicycles. On twin bikes both riders pedal and contribute according to their individual strength and abilities.

A: Yes. Models with quarter turn connectors can be taken apart into single bikes using a screwdriver. Models with manual and push button quick release pins, currently under development, require no tools.

Each bike can be used separately and makes storage and transportation simpler.

A: No, a “generic” link bar kit is not feasible. Location of link bar connection points and link bar lengths are critical for correct functioning and are specific for different frame geometries.

High-quality step-through city bikes can be converted into side-by-side flexible twin bicycles. We are testing a connector system that attaches to frames without welding or removing the original manufacturer’s paint finish, with potential applications for lightweight aluminum bicycles. However, professional design and installation is required for proper link bar length, pivot point placement, Ackermann steering geometry, and frame alignment.

A: Possibly. We reviewed several designs but postponed development due to other priorities and to the complexity of this type of link bar system.

An option is to use two medium-sized frames and adjust for rider size differences by varying saddle heights, saddle offset, and handlebar stem lengths.

A: Yes, there are.

•Van Raam offers a range of innovative models, including a rigid side-by-side tandem equipped with electric motor and pedal assist option.

•Roam Special Cycles provides the "Twinbike Split," a rigid model comparable in size and weight to our Prototype 6. It seems to be easily separated into two individual bicycles.
