HP Velotechnik Delta TX Video Review and Ride Test:

The Dignified Way to Be Mobile on Three Wheels

Note: HP Velotechnik trikes are custom made for you in Germany.  Please contact for assistance in configuring your perfect Delta TX!  Options include lighting, bags, racks and locks.  Prices are a guideline and subject to change based on exchange rates and do not include accessories.

With the comfortable Delta tx, safe cycling is easier than ever before! This starts as soon as you mount: The high seating position of the Delta tx and the low, comfortably suspended frame are an invitation to take a seat. Thanks to the variable seating systems, you’ll quickly find your premium position and enjoy the most expansive field of vision in traffic, secure stability at all times when stopping at traffic lights, and a panoramic view when riding in the country.

The controls on the handlebars are ergonomically arranged and always in view. Steering, gearing, braking: everything is very easy to manage. Above all, you get support in every situation: All Delta tx trikes from HP Velotechnik are equipped with an electric motor including a push assist up to 6 km/h (4 mph).

Your comfort plus: You can optionally choose a fully automatic drivetrain. Then all you have to do is pedal, your bike will select the appropriate gear. This is a perfect match for this comfortably suspended chopper trike with its dignified riding characteristics.

The Easiest Entry Into the Trike Class

A superior riding experience with high tipping stability: the seat is positioned between the rear wheels with a favorable center of gravity. The low position of the motor, battery and the generously dimensioned luggage basket also ensures safe riding.

Easy in every respect: The Delta tx with its sturdy aluminum frame weighs in at a slim 32 kg (71 lbs) in its lightest version. Your lightweight Delta tx excels in the premium league of motorized tricycles!

Split for transport: In just three minutes you can dismantle the Delta tx into three parts to save space, e.g. for transport in the car. The front section has a packing size of 119 x 60 x 42 cm (47″ x 24″ x 16″, L x H x W, with pedals), the rear section 100 x 75 x 60 cm (39″ x 30″ x 23″, with handlebars and including the optional platform carrier for the basket).

How to Split the Delta TX

Individual Seating Comfort

Adjust & Relax

The breezy ErgoMesh and ErgoMesh Premium mesh seats are available in four sizes each. On the two high HS variants, you sit 11 cm (4.3″) higher; the two XL variants are 5 cm (2″) wider. All seats can be individually adjusted to your back shape with OrthoFlex®-technology and several tension belts. And all seats can be optimally adjusted on the trapezoidal profile of the frame to suit your leg length and body size.

Premium advantage: With the ErgoMesh Premium, you can adjust the angle of the backrest and seat base independently. This allows for maximum individual seating comfort.

Komfort-Dreirad Delta tx Gangschaltung Enviolo Trekking Automatiq


Fully Automatic? For Sure!

Many cyclists love to shift extensively to always pedal in the optimal range. With our automatic gearing systems, you always drive in the optimal range – and don’t have to lift a finger. The Enviolo Trekking Automatiq hub as a complement to the Bafang motor changes the gear ratio not only automatically, but even without steps.

For the Shimano STEPS E5000 and STEPS E6100 motors, the automatically shifting Nexus Di2 hub is the ideal partner. And the powerful Shimano motor STEPS EP801 Cargo shines in combination with the electric automatic derailleur Cues Di2.

Your advantage: With our automatic gear systems you always have the right gear engaged to speed up fast!
