The Delta tx was developed specifically for people who want a lot of support and comfort when cycling and therefore need a stable, tipping-resistant vehicle with a low entry height. “There’s a lot more riding fun with this trike!” Whether cruising in the city or shopping with plenty of storage space for the purchases: “The Delta tx is very well received across generations. You don’t need to be at a certain age to enjoy the casual riding position on a Delta tx.
With all the innovations in the Delta tx, however, HP Velotechnik also uses its expertise in seat technology developed over many years. An outstanding feature of the Premium seat comes into its own here: with it, the backrest and seat surface can be adjusted independently of each other. For a bike with the highest comfort requirements, this is the perfect complement.
Continuous adjustability on the trapezoidal profile of the frame allows both the ErgoMesh and the ErgoMesh Premium to be adapted to the user’s body size and preferred sitting posture. Both seats are available in two heights and widths. And for more, they can be individually adapted to the shape of the back using Orthoflex padding technology.
The Delta tx is the first model at HP Velotechnik to be designed purely as an e-bike. Four systems are available for the Delta tx, all four can be optionally equipped with fully automatic shifting.
The basic model features the M300 from Bafang. The smooth-running, rotation-controlled mid-motor develops its full power independently of the pedaling force. This is especially helpful for people with low leg strength and feels like riding with a throttle on the strongest support level.
For more robust support in hilly applications, it’s the Shimano STEPS EP801 Cargo with torque sensor technology: If you pedal harder, you also get more thrust from the motor. The EP801 offers a lot of power right from the first pedal stroke, especially with a high payload.
The EP801 Cargo finds an ideal partner in combination with the new automatic 10-speed derailleur Cues Di2. Alternatively, HP Velotechnik also installs the Enviolo Trekking Automatiq for the EP801 Cargo drive or, for fans of manual shifting, the classic from Rohloff, the Speedhub with 14 speeds.
Freewheelin Twin technology means that only the inner wheel is driven when cornering. An additional advantage over the differential is a driving situation that is quite familiar to tricyclists: If a rear wheel spins on loose ground, for example when starting uphill on gravel, then a differential directs the entire drive force precisely to this spinning wheel. The result: you can’t move. This is different with the Freewheelin Twins, where the power is automatically directed to both wheels and the Delta tx has grip even in such situations.
“The Delta tx should be able to be made very compact to take wherever you wish to ride, especially in the car.” With the Delta tx, the designers aimed for ease of disassembly into separate, easy-to-handle parts. “After the seat is removed via quick release, it only takes an Allen wrench to remove the handlebars and then disassemble the main frame into two parts.”
