Stability and safety

We design specific bicycle hitches that are fixed close to the rear wheel axle of the suitable bikes.

The hitches are fixed to the frame with existing holes (mudguard, brake caliper, rear rack) or with special clamps.

About the 'Universal' hitch


In order to adapt to the different geometries of bicycle frames, we have developed the 'universal' hitch. Its arms are adjustable to match the frame of the bike.

To use it you must ensure that you have room to install the clamps. Minimum of 3 clamps installed as far as possible from each other. Different sizes (12 and 18 mm) are supplied. 24 mm on request.  Be aware of the placement of the brake caliper, cables or the kickstand when installing the hitch.

The ball must be at a height of ~360 mm from the ground and within 390mm of the rearmost point of the bike.

As an option, we offer a suitable bikestand that can be attached directly to the universal hitch.

How to choose your bike ?

The BicyLift and Runner are professional trailers and require professional quality bikes for a safe and reliable use.

We do not impose a model but recommend parameters that we consider important:

Robustness

Forget the racing bike, prefer a more robust frame and equipment (wheels, tires, transmissions,...) 

Braking capacity 

For the trailer brakes to activate, the bicycle brakes must work under all conditions. Therefore, hydraulic disc brakes are recommended.

Transmission 

Gear hubs allow you to change gears when stationary.
Derailleurs are easier to repair. 

Electric assistance

Unless you are in a flat area and do not tow heavy loads, the use of an electric-assisted bicycle seems essential. Various types of assistance exist. We recommend mid-motors with a torque of at least 80Nm (Bosch Performance CX, Bosch Cargo Line, Shimano step8000, Shimano EP800, Brose drive S).   

Load capacity 

Depending on your activity, you will have a greater or lesser interest in being able to carry goods on the bike in addition to loading the trailer. Combined with the delivery of a pallet, you could thus ensure some additional poses of packages on the way.

Stability when standing still

A stable bike stand avoids significant stress on the trailer hitch, the coupling and the bike. Prefer a side bike stand attached near the rear hub which offers good stability when coupled to our trailers.

            Why are the trailers coupled near the rear hub of the bikes ?

            For stability, thus safety. With this configuration, the trailers cannot tip the bike over in curves or when the bike brakes. When the trailers are attached to the seatpost, it is way easier to lose equilibrium. Seatposts are also not designed to pull heavy loads.

            Our hitches are also designed to ensure the safety of the cyclist in the event of a crash with a vehicle coming from behind. The hitch is designed to break in order to preserve the bike and protect the cyclist.
