Sports Utility Bikes

Current cargo bikes are either too big or can't carry much luggage.

SUBs have a low centre of mass and three wheels making luggage carrying safe and stable. The dual-steering system provides safety at high speed, and great manoeuverability at low speed.

To leave our cars at home, cargo bikes need to be better!

The small wheels used on modern scooters will never be safe.

Hub steering includes enough camber for high-speed, straight-line stability and is well proven on recumbent trikes. Eight degrees is sufficient for the tightest corner or roundabout.

Pivot steering provides incredible manoeuverability but has no self-centering or protection against turning moments due to impacts against one wheel. This means it is only safe to be used at low speeds.

Switching between the hub and pivot steering is automatically controlled by our unique steering system design. Patents applied for.

Riders can lean into bends with great high-speed cornering stability, then manoeuvre around tight areas without losing any luggage carrying capability.

Carry up to 40kg, low down, safe, and stable. No side-stand required.

The design provides enough space for a toddler's child seat to fit between the wheels.

The seat and handlebars are fully adjustable to give a one size fits all capability.

The wheel, seat, and pedal layout and sizes are based on common dimensions from traditional bikes.

This version uses hydraulic steering to provide better load feedback and a more flexible testing program.

Simply lifting the middle of the bike and the rear suspension pivots to fold the bike away.

This feature allows the frame to be locked securely together. No chain is required and only cutting through the frame will allow it to be taken. It can also be folded and locked around a post, to stop it from being taken away.

The folding action also closes the space under the frame or rear swinging arm, where the battery is stored. Providing extra security for whatever extra you store inside the cavity.

The electric motor is contained within a removable box. This means that a separate 'pedal only' version can be fitted or the bike can be upgraded with a different electric motor design, so it will never go out of date.

Rear suspension is via rubber cushions. Front suspension can be facilitated by the cantilever arm design.

Simply lift the middle of the bike to fold it in half.

The cavity inside the frame could be used for secure storage.

Waterforce-activated mudguard brushes are used to stay dry and reduce wind resistance.

Belt drive can be used for cleanliness when folding.

The improved suspension will allow solid tyres to be used and therefore punctures eliminated.

A three wheeled bike will potentially allow a rain cover so the riders can stay warm and dry when it rains.

This was our first concept trial.

This version included cable steering with mechanical switching between hub and pivot steering.
