Those looking for a Super73 alternative usually don't just want to buy any e-bike. They are looking for a special riding experience: wide tires, a long seat, a compact frame, and the striking look of a retro moped.
SUPER73 has made this style internationally famous. At the same time, many interested parties are now comparing different alternatives – for example, due to price, features, warranty, availability, service, or the question of which version can be used sensibly in Germany.
In this guide, you'll learn what matters when choosing a Super73 alternative in Germany and how the Rockbike Rumble, a 20-inch e-fatbike in retro moped style, fits into this category.
Key points at a glance
- A good Super73 alternative should not only look similar but also fit body size, usage, and budget.
- SUPER73 offers various series and models with different features.
- For buyers in Germany, the specific European vehicle version is particularly important.
- Motor control, continuous rated power, assistance speed, and bicycle equipment must match the intended use.
- The Rockbike Rumble combines 20 × 4 inch fat bike tires, a long seat, and retro moped design.
- Warranty, spare parts, and an accessible contact person should be considered when comparing.
- Technical specifications must always be compared based on the specific model and the current product page.
Why do buyers look for a Super73 alternative?
SUPER73 stands for e-bikes that visually resemble small motorcycles or mopeds more than classic city or trekking bikes. Many interested parties like exactly this style but want to compare several offers before buying.
Typical reasons for looking for an alternative are:
- a different price-performance ratio,
- a longer warranty,
- a specific tire size,
- hydraulic disc brakes,
- a more compact or lower design,
- a German contact person,
- quick availability,
- an easier-to-understand product configuration,
- a specific range or battery size,
- a pedelec version intended for Germany.
An alternative should therefore not just be seen as a "cheaper Super73". What matters is which bike better meets one's overall requirements.
What characterizes the typical Super73 style?
Buyers looking for an e-bike like Super73 usually mean a specific combination of design and riding feel.
Long Seat
Instead of a classic bicycle saddle, many retro e-fatbikes feature an elongated, padded seat. This creates the typical moped silhouette.
A longer seating area can allow the rider to shift their position slightly forwards or backwards. However, whether the seating position is truly comfortable also depends on handlebar height, frame length, and pedal position.
Wide Fat Bike Tires
Wide tires are one of the most striking features of this vehicle class. Tire sizes like 20 × 4 inches are frequently used.
The large tire volume can absorb minor bumps and provides the powerful look of a fat bike. Tire pressure, tread, and tire quality influence comfort, rolling resistance, and handling.
Compact Retro Frame
The frame of many models runs relatively low and long. The battery and electronics are often integrated in such a way that the bike looks more like a small moped than a conventional bicycle.
Upright Seating Position
A high handlebar and a long seat can enable a relatively upright and relaxed seating position. However, the actual ergonomics must still fit the individual body height.
Distinctive Headlight
A large headlight in a retro housing is part of the design of many bikes in the Super73 style. For use on public roads, not only the appearance but also the specific lighting equipment is crucial.
What features should a good Super73 alternative have?
An outwardly similar frame shape is not sufficient for a meaningful comparison. Several technical and practical points should be checked before purchasing.
1. Transparent Technical Data
The product page should clearly state:
- continuous rated power of the motor,
- maximum speed of motor assistance,
- battery voltage and capacity,
- brake type,
- tire size,
- vehicle weight,
- permissible payload,
- recommended body height,
- scope of delivery,
- warranty conditions.
Incomplete or contradictory information should be clarified in writing before ordering.
2. Suitable Body Height
A bike can appear compact visually and still be suitable for taller riders. Crucial factors are frame geometry, seat length, handlebar position, and pedal distance.
You can find detailed information on this in our guide: 20-inch e-fatbike: advantages, body height, and areas of use .
3. Reliable Braking System
Retro e-fatbikes are often heavier than classic bicycles due to their steel or aluminum frames, battery, motor, and wide tires. The braking system is therefore a central purchase criterion.
4. Realistic Range
Range specifications depend on factors such as rider weight, assistance level, temperature, wind, inclines, tire pressure, and terrain.
A advertised maximum range should therefore not be understood as a guaranteed range for every ride.
5. Service and Spare Parts
With an e-bike, questions about the battery, motor, display, controller, brakes, or tires can arise during use. An accessible contact person and available spare parts are therefore relevant in the long term.
Super73 Alternative in Germany: What are the legal requirements?
Anyone who wants to use a retro e-fatbike in public road traffic must check the specific vehicle version.
The following features, among others, are relevant for classification as a regular pedelec:
- a maximum of 250 watts of continuous rated power,
- motor assistance generally only while pedaling,
- reduction of assistance with increasing speed,
- motor assistance switching off at 25 km/h at the latest,
- start-up or push assistance without pedaling up to 6 km/h at most.
The legal definition is contained in § 1 Paragraph 3 of the Road Traffic Act .
In addition, a bicycle for road traffic requires, among other things, suitable brakes, lighting, reflectors, and a bell.

Do not confuse European and international versions
Videos, tests, or product descriptions from other countries may refer to a different technical vehicle version.
When comparing, therefore, always check:
- For which market was the tested bike built?
- What continuous rated power does the offered version have?
- Up to what speed does the motor assist?
- Is there a throttle and what function does it have?
- What documents belong to the specific version supplied?
Important: A US test or an international product video is not automatically transferable to the version of the same model offered in Germany.
20 inches, body height, and seating position
Many Super73-style bikes use compact wheels in combination with very wide tires. The designation "20 inches" does not automatically mean that the bike is only suitable for children or teenagers.
More important for the actual fit are:
- frame length,
- distance between seat and handlebars,
- height and shape of the handlebars,
- position of the bottom bracket,
- length of the seat,
- reachability of the brake levers,
- safe control of the vehicle weight.
Why a test ride is helpful
During a test ride, you should check whether:
- the handlebars are comfortably within reach,
- both brake levers can be operated safely,
- the knees have enough space when pedaling,
- the bike can be controlled when stopping,
- the seating position remains comfortable even after a longer ride.
Compare motor, battery, and range
Rated continuous power instead of maximum advertised values
When referring to motor specifications, a distinction should be made between continuous rated power, short-term peak power, and torque.
For the legal classification of a pedelec, not only the highest advertised power value is decisive. The documented continuous rated power and the actual motor control are important.
Sensibly compare battery capacity
Batteries should ideally be compared based on the stored energy in watt-hours. The watt-hours are derived from voltage and amp-hours.
Additionally, it should be checked:
- Is the battery removable?
- How long does a full charge take?
- Is a replacement battery available?
- What are the warranty conditions?
- How is the battery secured against unauthorized removal?
Realistically assess range
Large range specifications often arise under favorable test conditions. In everyday use, stronger assistance levels, cold, headwinds, inclines, and low tire pressure can reduce the range.
Those who commute regularly should therefore not only consider the maximum manufacturer's specification but also plan for a sufficient reserve.
Brakes, tires, and riding comfort
Mechanical or hydraulic disc brakes?
Mechanical disc brakes are operated via a Bowden cable. Hydraulic disc brakes transmit braking force via a hydraulic system.
Hydraulic brakes can offer well-modulated braking power and a clear pressure point. However, quality, correct installation, and regular maintenance remain crucial.
20 × 4 inch Fat Bike Tires
Wide tires provide the typical look of a retro e-fatbike. The large air volume can absorb bumps and provide a comfort-oriented riding experience on firm gravel or poor asphalt.
At the same time, wide tires can create more rolling resistance. The appropriate tire pressure influences comfort, grip, range, and steering behavior.
Suspension
A suspension fork can improve comfort on uneven roads. However, full suspension is not automatically necessary for every user and often increases weight, complexity, and maintenance effort.
Compare warranty, service, and spare parts
When comparing a Super73 alternative, not only the purchase price should be considered. Warranty and service can make a significant long-term difference for an e-bike.
These questions should be clarified before purchasing
- How long does the manufacturer's warranty last?
- Which components are covered?
- Are there special conditions for the battery?
- Who is responsible in case of a complaint?
- Are wear and spare parts available?
- Where are repairs carried out?
- Are there transportation or labor costs?
- Is there a German-speaking contact person?
SUPER73 currently states a 24-month warranty on manufacturing defects on its European website. For the battery, 24 months or 500 charging cycles are mentioned – whichever comes first.
The full conditions can be found on the official European SUPER73 warranty page .
SUPER73 or Rockbike Rumble?
A direct comparison is only possible to a limited extent, as SUPER73 offers several series and models with different equipment. The Rockbike Rumble, on the other hand, is positioned as a focused single model in the 20-inch retro segment.
| Feature | SUPER73 Europe | Rockbike Rumble |
|---|---|---|
| Product Selection | Several models from the Z-, S-, and R-series | Focused 20-inch retro e-fatbike |
| Design | Model-dependent motorbike and lifestyle style | Retro moped design with long seat |
| Tires | Varies depending on model | 20 × 4 inch fatbike tires |
| Motor and Assistance | Check specific European model page | 250-watt rear motor and assistance up to 25 km/h according to product page |
| Brakes | Model-dependent | Hydraulic disc brakes with 180mm rotors |
