Delta tx – The Chopper E-Trike for Everyday Life and Leisure
The Dignified Way to Be Mobile on Three Wheels
The comfortable Delta tx makes safe cycling easier than ever before! It starts as soon as you get on: The high seating position and low-slung frame of the Delta tx make it easy to get on and off, while the variable seat systems allow you to find your perfect position in no time. You’ll enjoy an excellent overview of traffic, a secure position when stopping at traffic lights, and a panoramic view on a country ride.
The controls on the ergonomic handlebars are always easy to reach, making steering, shifting gears, and braking a breeze. Wonder what the best part is? You’ll receive support in every situation! All Delta tx trikes from HP Velotechnik come equipped with an electric motor up to 25 km/h (16 mph) or up to 20 mph for the USA, including a push assist up to 6 km/h (4 mph).
Four motor systems with different power profiles are available, and you can choose a fully automatic gearshift for each of the motors. Simply pedal in your own pace, your Delta tx trike will select the right gear for you!
Crucial for the stable riding characteristics is the comfortably suspended frame. The suspension element underneath the seat can be individually adjusted to your weight and a total load of up to 145 kg (320 lbs). The voluminous Super Moto-X tires developed by Schwalbe especially for e-bikes roll extremely smoothly. With their 62 mm (2.4″) width the tires also offer plenty of grip, even on poor roads.
Delta tx
The Easiest Entry Into the Trike Class
A superior riding experience with high tipping stability: The seat is positioned between the rear wheels to optimize the center of gravity, while the low position of the motor and battery, as well as the generously dimensioned and deeply positioned luggage basket, ensure a safe and stable ride.
Top class: The Delta tx is lightweight in every aspect. With its sturdy aluminum frame, the lightest version weighs just 35 kilograms (78 lbs) including motor and battery. Your lightweight Delta tx excels in the premium league of motorized tricycles!
Transporting your trike is easy: The Delta tx is separable for transportation, allowing you to disassemble it into three space-saving parts in three minutes. You can easily lift them into your car and still have enough space for your luggage. For maximum mobility, you only need a minimum of tools – a 5 mm Allen key!
Make your own choice: We offer the Delta tx in two versions. With the Special Edition models (SE models), you don’t have to spend time evaluating the many possibilities of our modular system. You will receive your trike almost fully equipped with a versatile set of components, based on our many years of experience as a custom bike manufacturer. If you opt for a Delta tx in the modular system, you can choose your favorite options and have your E-Chopper built exactly according to your wishes. Your HP Velotechnik dealer will be happy to advise you!
Smooth and Comfortable
Inch by Inch Ingenious Design
Take hold! The ingenious design ensures smooth directional stability and maximum flexibility. With a turning circle of just 3.20 meters (10’5″), you’ll be able to navigate even the tightest spaces with ease.
Not an inch too high: The Delta tx achieves a comfortable step-through height of just 35 cm (12.6″) by elegantly positioning the cables and the smooth-running chain guard low against the frame. No shoe will get stuck.
Not an inch too wide: At 75 cm (29.5″), the Delta tx is conveniently narrow. This means that you can also ride on narrow paths without any problems. And if you want to take your trike through your gate and door to park it, you can easily roll inside.
Your Seat, Your Throne
Our Mesh Seats – Maximum Ventilation and Adjustability
At HP Velotechnik, we believe that the key to a comfortable ride is a really comfortable seat.
That’s why we have developed the Delta tx with the utmost attention to seating comfort. Our ErgoMesh and ErgoMesh Premium seats are designed to provide maximum ventilation and adjustability. You can choose between two heights: the standard or the HS version, which is 11 cm (4.3″) higher and provides a better overview. Depending on your height and therefore the position of the seat on the frame, you can sit at a height of 59 to 71 cm (23″ to 28″).
Go wide: The ErgoMesh and ErgoMesh Premium seats are also available in two sizes. The XL seats are each 5 cm (2″) wider compared to the standard size. Their backrests are also slightly higher and the seat bases slightly deeper. You can adjust the shape of the seat to your body by tightening or loosening the tensioning straps on the back of the seat.
Our OrthoFlex® technology ensures that even the standard ErgoMesh mesh seat offers plenty of scope for further ergonomic adjustments. It consists of four highly breathable cushions that can be individually cut to size. You insert these 3D cushions into the sides of the seat and backrest and adjust them according to your preferences.
For the ultimate in comfort, our ErgoMesh Premium seat offers independent adjustment of the inclination of the backrest and seat base within a range of 25°. With the optional Seat angle adapter, you can raise the backrest up to a further 9° steeper.

From Shopping to Touring
Want to Ride Fully Loaded? We’ve Got You Covered!
Secret competition for cargo bikes: Transform your trike into a versatile transporter! With our various luggage systems, you can carry a total up to 50 kg (110 lbs) of cargo easily, safely and with optimum suspension on your Delta tx. Are you looking for a trike that can carry all your luggage with ease? Look no further!
The Delta tx is designed to accommodate as much luggage as possible with the lowest possible center of gravity. Regarding this aspect, the space between the rear wheels is the logical choice for accommodating a practical transport basket. Due to the elegant design of the comfortable E-Chopper, this space is so generous that HP Velotechnik has developed an extra-large basket for you! You can easily remove the 25 cm (9.8″) high container by the handle and turn it into your shopping companion.
You can also use the trike without the basket and load a large crate of beverages, for example. The platform carrier is securely attached to the suspended part of the frame and has a comfortable loading height of 38 cm (15″). The internal dimensions are 48 x 32.5 cm (18.9″ x 12.8″) and the maximum load is 25 kg (55 lbs).
Above the platform carrier with the large basket, there is still plenty of space for a standard bike bag. Simply hang it in the optional Bag mount behind the seat to carry up to 12 kg (26.5 lbs) of extra cargo.
Additionally the Add-on bags designed by HP Velotechnik can be attached to the right and left of the seat. The practical bags, each with 1.4 liters of storage space (1.5 kg or 3.3 lbs), are easy to clip on and off – your highly variable companion on a day trip.
Small luggage, right at hand: Our Side bag mounts are the perfect option for attaching standard handlebar bags to the right, left or both sides of the seat. The load capacity of each is 5 kg (11 lbs). And if you want to keep things really cool, you can also fit the practical holders with a standard bicycle cup holder.

In addition to the platform carrier, you can opt for the Trailer coupling option. This allows you to pull a child or cargo trailer behind you with a total weight of up to 40 kg (88.2 lbs).
Stepless Adjustment & Easy Split
One Frame Size for the Whole Family
The main frame of the Delta tx comes always in one size. It offers space for people between 1.59 (5’2″) and 2.00 meters (6’7″) tall. For stepless adjustment, simply open the two quick-release levers to slide the seat on the frame.
The handlebar system is also adjustable in length and height. The elegantly curved standard stem conveys a real chopper feeling, while the shorter, straighter version makes the steering feel more dynamic and responsive. The short stem is also recommended for people under approx. 1.70 m (5’6″) tall. This means that the Delta tx also offers plenty of scope to adjust it to your individual preferences for arm and hand positions.
Easily separable: The Delta tx can be split into three parts in around three minutes. The only tool you need is a 5 mm Allen key. The front section has a packing size of 119 x 60 x 42 cm (46.8″ x 23.6″ x 16.5″; L x H x W, with pedals), the rear section measures 122 x 75 x 60 cm (48″ x 29.5″ x 23.6″; with handlebars and platform carrier).
The seat can be easily stowed next to it for transportation in your car. The weight of the two frame parts is approximately the same, namely around 16 kg (36 lbs) each. This is a great advantage after splitting the trike when lifting the individual parts!

Electric Assist
Always With Motor! And a Fully Automatic Gearshift on Request
You can choose from four different electric motors for your Delta tx. All of them are bottom bracket motors that provide additional assistance up to 25 km/h (16 mph), or up to 20 mph in the USA. The basic version comes with the M300 from Bafang. Regardless of how forcefully you pedal, it unleashes its power as soon as you start pedaling. You don’t even need a throttle for this. The rotation-controlled system offers five power levels and helps you to ride home relaxed even when you start feeling tired.
If you appreciate a more sporty feeling, choose one of the three torque-controlled Shimano STEPS motors: the more powerful you pedal, the more assistance the system provides. The E5000 system is ideal if you are looking for a motor with a medium level of assistance at an attractive price. The E6100 provides 50 percent more torque power. The high-end EP801 Cargo system provides 85 Nm and 600 W maximum power for rapid acceleration from the very first pedal stroke.
Many cyclists love to shift gears extensively in order to always pedal in the optimum range. With our automatic gearshifts adapted to the motor profiles, you always ride in the optimum range – without having to lift a finger. While you are waiting at a red light, for example, your system has already shifted into the right gear.
The Enviolo Trekking Automatiq hub is an ideal addition to the Bafang motor. It not only changes the gear ratio automatically, but even without steps!
For the E5000 and E6100 motors,the Nexus Di2 8-speed hub is a great partner. With the top model, the powerful EP801 Cargo, you have the choice between the continuously variable Enviolo or the Cues Di2 from Shimano. The Cues is fascinating as the world’s first electric automatic derailleur. Even when you are not pedaling, the chain continues to rotate as required and, thanks to the Autoshift function, ends up in the gear that suits your speed.
Of course, we also have something in our range for fans of traditional manual gearing: the classic encapsulated hub gear, the Rohloff Speedhub. The very low-maintenance 14-speed drivetrain, which is often chosen by experienced riders for challenging conditions, can be easily operated using the twist grip.

The Details at a Glance
Your Delta tx electric comfort scooter trike has these technical refinements on board as standard.
The chopper handlebar is adjustable in height and length, so you can easily set up your trike for your body size and to your preferred arm position
Maneuvering made easy: The steering is designed for smooth straight-line stability. Nevertheless, your Delta tx can turn almost on the spot. The turning circle is just 3.20 meters (10'5") wide.
The headlight swivels with the steering and illuminates the road exactly where you want to go. In the standard version, Busch+Müller’s small and elegant IQ-XS eco friendly provides up to 80 lux. The optional top model IQ-X even offers up to 150 lux of brilliant light.
With an overall width of 75 cm (2'5"), the Delta tx is exceptionally slim. So you can easily get through narrow traffic bollards. Even the narrow gate of a garden shed is no obstacle if you want to park the bike safely.
The Delta tx achieves the comfortable step-through height of just 35 centimeters (13.8") by hugging cables and the smoothrunning chain guard tubes low and elegantly to the frame
Fat tires: The Super Moto-X underline the solid looks of your Delta tx. Schwalbe developed these extremely smooth rolling tires especially for e-bikes. The voluminous 62 mm (2.5") tire width ensures a comfortable ride and good grip on bad roads.
Good traction:With HP Velotechnik’s drivetrain technology, both rear wheels are driven when driving straight ahead. When cornering, you have powerful propulsion without the need for a complicated differential gear.
The fully suspended platform carrier at the rear is generously sized with an internal dimension of 48 x 32,5 cm (19" x 12.8"). The carrier comes with a 25 cm (10") high shopping basket. And yes, if you take that out, you can even carry a standard German beer box on the platform!
Well protected and fully integrated: The motor and battery blend harmoniously into the overall appearance of the Delta tx.
To protect you and your clothing from rotating parts, we install low-friction chain guard tubes. At the rear end, the intermediate gears and sprokkets are conveniently covered.

Add-on bags
The optional Add-on bags behind the seat are ideal for your small luggage. The left pocket has an airy mesh fabric on the side, ideal for stashing the optional Rain cover. That allows the contents to dry while you continue your journey.
Bag holder

Rear mirror
With the extra large viewing angle of the B+M Cycle Star E mirror, you can see what's going on behind you. The field of view is easily adjustable, but remains in position even on rough surfaces.

Bike flag
Safety is not a fashion statement: Many recumbent riders enjoy using a Flag to increase visibility in traffic; it belongs on their ride like a bell or horn. Our new logo and design brings a fresh level or awareness on the road to everyone. Silver reflective with orange print.
Anti-tip wheels
The Anti-tip wheels increase safety in extreme riding situations, for example on inclines or when starting off with a lot of power. Recommended for: tall riders, with a high seat, with a Bag holder, with a high luggage load; always with the extra powerful drive option Shimano STEPS EP801 Cargo.
