Trike concepts: two wheels in front or in back?

All of our trikes are deltas, meaning they have two wheels in the back and one wheel in front. Why? Because this design has numerous advantages … many of which are described here.
In case you were wondering, there are several reasons why we only build trikes with one front and two rear wheels. The other trike design is the tadpole: two front wheels, one rear wheel.

Maneuverability and safetyWith delta trikes, the front wheel is mounted on a classic bicycle fork with the corresponding headset bearings. All that is required for connecting the handlebars to the front wheel is an adjustable steering linkage. Our maneuverable deltas can turn on a dime, whereas the tadpoles have a much larger turning radius owing to their design.

Powerful on slopes and off roadAt the rear of the trike, there are also significant functional differences between the two concepts: the driven rear wheel of a tadpole trike tends to lose traction on loose surfaces or if a trail gets too steep, particularly if the trike has an electric pedal-assist system. The same effect can be seen on delta trikes with one driven wheel. This is why our trikes are also available with a differential. This feature transmits power to both rear wheels. Owing to the favorable weight distribution – with the rider sitting practically between the two rear wheels – a delta with a differential boasts much better traction. This not only makes for a very sporty ride, but also adds safety.

More safety when getting on and off the trikeDelta trikes are much easier to mount. Just lower yourself onto the seat as if it were a normal chair. Then, once you are in this safe sitting position, all you have to do is lift one leg over the frame, and you’re ready to go.

Safe handling and a good overviewThe seat’s position between the two rear wheels makes the trike extremely stable, even when the seat is raised. The delta design offers the rider a better view of traffic without sacrificing sporty handling.

High load-carrying capacity with good road-holdingAny standard pannier can be attached behind the seat of a HASE BIKES trike. However, we have also developed our own special cargo-carrying system: the large version of our ROLLER BAG can handle up to 100 liters (15 kg/33 lb) of luggage or supplies. And as a bonus: a loaded trike has even better road-holding properties!

The power comes from the middleWe’ve adapted the Shimano Steps mid-motor for use with our trikes. Mounted at the bottom bracket, the drive can deliver power to both rear wheels via the chain and differential. The system is so silent and smooth that it’s practically unnoticeable – the trike simply feels unbelievably light and sails effortlessly up any hill.

Joining two to make oneAnother advantage over the tadpole design is that it’s easy to connect our delta trikes to create trike tandems (using the HASE BIKES tandem coupling). Triking as a team is not only a fun pastime – but also an efficient means of traveling with riders whose ability to be independently mobile is limited.

In summary – the following is a brief list of the delta’s advantages:– great maneuverability and a small turning radius
– excellent traction (with differential)
– more safety when getting on and off the trike
– foldable frame
– easy to push backwards by picking up the front wheel
– can be parked on end
– good overview of traffic (especially with our high-comfort LEPUS models)
– flexible cargo transport, high load capacity (with HASE BIKES ROLLER BAG)
– very harmonious electric drive system with the Steps mid-motor
– fast and easy conversion to a trike-tandem
