FAQ – Frequently Asked Questions
How do I find the correct frame size for my bike?
Which size suits you best is best determined by consulting your certified STEVENS dealer and a test ride. Your dealer is experienced and has a trained eye. Maybe they will offer you several sizes of the same model. The most important thing is you to feel comfortable on the bike.
As every single body has different proportions – lengths of legs, arms, and upper body – it is difficult to make general statements via remote diagnosis. Also, individual preferences of how to sit on the bike are to be considered.
The following formulas may help you with a first assessment:
Stand with your back against a wall, at best wear nothing but underwear, and put a book, a level or the like between your legs with its spine firmly up against your crotch. There should be a right angle between legs and book. Measure the distance from the floor to the spine of the book with a tape measure or folding rule.
To determine frame size, multiply the measured number for the different bike types as follow
- Trekking or touring bike: 0.66
- Road bike: 0.66 + 2
- Mountain bike hardtail: 0.226 (for frames specified in inches)
- Mountain bike fully: 0.225 (for frames specified in inches)
If the resulting number is between two frame sizes, we advise you to go for the smaller frame size. Please keep in mind: this value only indicates the correct size of the seat tube, not how stretched out or upright you sit on the bike!
Where do I find information on older STEVENS bikes?
All information on bikes of STEVENS' model years up to 2010 can be found here under production years. As usual you will find detailed information on specs, colour options and geometry.
It is very likely, however, that those models are no longer commercially available.
What Exactly Is a Pedelec?
Pedelecs (Pedal Electric Cycles) also EPACs (Electrically Power Assisted Cycles) are bikes with an electric motor that only engages as long as the rider is pedalling. As soon as you stop moving the pedals, the motor shuts off.
A pedelec is legal to ride without a license if the motor switches off when speed reaches 25kph (15mph). You also don’t need an operating permit or a license plate (in difference to a “fast pedelec”/”speed pedelec”(S-pedelec)).
Legally pedelecs are treated as bicycles, they’re allowed to be ridden on bike lanes and even obliged to in areas where using a bike lane is mandatory for bikes. We highly recommend wearing a helmet when riding, even if it is not mandatory by law in your country/area.
STEVENS Allround Pedelecs are exclusively designed to be ridden on trails and roads with a smooth surface. Please only ride on routes that are legally cleared to be accessed by bicycles.
For off-road use the only suitable bikes are STEVENS Offroad Pedelecs. Please refer to the chapter “intended use” in your STEVENS quick user guide as well as your pedelec manual.
What Exactly Is a Speed Pedelec?
Speed pedelecs (or in short S-pedelecs) according to EU regulations are legally treated as “lightweight motor cycles with low power” (L1e) whose electric motor will also deliver support at speeds over 25kph (15mph) up to 45kph (28mph) as long as you keep pedalling. S-pedelecs also will propel your bike without pedalling along to a maximum speed of 20kph (12mph).
Since S-pedelecs are considered motor cycles (class L1e) according to EU guide line 2002/24/EG, they require an operating license or an EU type approval certificate and are subject to strict guide lines in terms of components and modifications. To be road legal you need an operating license, a license plate and proper insurance. Most countries require a driver’s license for the operation of S-pedelecs on public roads. Please check your country’s/area’s laws regarding these requirements. Also in most countries you may not use STEVENS Speed Pedelecs on inner-city bike lanes unless those lanes are legally cleared for access with small motor cycles. Please check your local laws before riding a speed pedelec on public roads.
In most countries also wearing a helmet is mandatory when riding an S-pedelec. Please refer to the chapter “special requirements for riding STEVENS Speed Pedelecs” in your STEVENS pedelec manual.
How Many Kilometers Does My Pedelec Battery Last?
How far you can ride with a pedelec cannot be determined by a single data. The range of a pedelec system depends on a variety of different and sometimes changing factors which all have an influence on the efficiency and electricity consumption of a pedelec. At the time there is no uniform industry-wide standard to define range.
The major factors to determine range are the technical properties of motor and battery – capacity measured in Watt hours (Wh) - and in which level of support the pedelec is ridden. Average speed and pedaling cadence also do play a role.
Other important aspects are the weight of the bike, rider and cargo adding up to the system’s overall weight but also tire profile and pressure and seating position which influences wind resistance – they all are affecting battery life.
Then there are environmental factors: The hillier the route and the stronger a head wind the more the motor has to work to overcome the additional resistance. Also the smoother the surface the less energy the pedelec uses. And many repeated stops and starts force the battery to consume more energy is required to propel the pedelec.
The ebike systems branch of BOSCH has developed a range assistant, featured on their web page, which takes into account all the factors mentioned above. On this page you can estimate the approximate range of your STEVENS pedelec. In addition to using the range assistant we also recommend to factor in some extra kilometers for safety to be prepared for spontaneous detours and, when possible, not only recharge your own battery but also that of your STEVENS pedelec.
How Do I Maintain my STEVENS Pedelec Battery?
The pedelec batteries by our supplier Bosch are efficient and long-lasting energy sources. Like all modern lithium-ion batteries they are prone to natural degradation, even when not in use. You can positively influence longevity by storing the battery at temperatures between 0°C and 20°C and charged between 30% and 60% of maximum capacity.
We recommend referring to the “eBike Battery Guide” by Bosch eBike Systems that features comprehensive information about maintenance, handling, charging times and more. Please also note the information about battery maintenance in the STEVEN Pedelec Manual.
Can I perform any alternations as I like on my STEVENS Pedelec?
Due to being equipped with an electric motor pedelecs are subject to the EU machinery directive. This entails several differences from a conventional bicycle in terms of operating in traffic and technical alterations. For example, a pedelec is required a CE marking and a declaration of conformity from the manufacturer. If you perform any permanent constructional alterations other than specific parts you will become a manufacturer yourself and you can be made liable in case of damage.
The basic rule constitutes that components can only be replaced by original components. In addition to that STEVENS dealers follow the “Guide Line for Exchange of Components on CE Marked E-Bikes/Pedelecs with Motor Support Up To 25kph”, recommendations by notable German bicycle trade organisations such as ZIV and VSF plus the Zedler Institute for Bicycle Safety.
According to the guide line replacement of parts like a bell or handlebar grips is no problem at all, but exchanging motor or battery is prohibited. Always ask your STEVENS dealer for advice in case you want to change anything about your STEVENS pedelec.
Can I Transport Children in a Trailer Or Child Seat On a Pedelec or S-Pedelec?
With a STEVENS All-Round Pedelec having a motor delivering support up to 25kph, it is legal to tow trailers (max. weight 40kg without an overrun brake, 80kg with an overrun brake installed).
Especially with pedelecs, STEVENS Vertriebs GmbH recommends using a trailer equipped with an overrun brake. It is also legal to mount a child seat on a pedelec 25. Please note that the weight of the trailer or child seat and that of the child(ren) and/or cargo in the trailer/child seat are all part of the maximum permissible weight of 140kg (309lbs) for STEVENS pedelecs.
It is not allowed, though, to pull a trailer with or mount a child seat on a STEVENS E-Fully.
Take your bike to the dealer when buying a child seat or (child) trailer. This way you can immediately see which seat fits, how exactly it’s adjusted or what type of trailer hitch is the best for your bike and trailer.
With speed pedelecs delivering motor support up to 45kph it is not legal to tow a trailer. It is allowed however, to mount or use a child seat on an S-Pedelecs. Please note that the weight of the child seat and that of the child are all part of the maximum permissible weight (140kg (309lbs) for STEVENS S-Pedelecs). Take your S-pedelec to the dealer when buying a child seat. This way you can immediately
Where Can I Find My STEVENS Bike‘s Frame Serial Number?
The frame serial number on many older bikes can be found under the bottom bracket, on current bike designs it is printed on a sticker on the down tube. Since model year 2008 the frame number has a very simple pattern. The first digit is an “S” followed by a sequence of numerals and if applicable by capital letters. Altogether the sequence is 10 to 12 characters long.
On My STEVENS Bike There Is a Sticker with a Picture/Icon and a Code Starting with “ISO” – What Exactly Does This Indicate?
This icon indicates for which kind of intended use the particular bike has been designed for. An exact definition of all individual icons/intended uses can be found in the manual in chapter “intended use”.
What Is The Correct Torque That I May Use To Tighten the Bolts On My STEVENS Bike?
To ensure the operational safety of your STEVENS bike all screw joints need to be securely fastened and checked on a regular basis. This is preferably done with a torque wrench that makes a clicking noise and disengages when it reaches the torque it’s been adjusted to. Approach by starting at a low torque and increasing it in small steps (0.5Nm at a time) in between consistently checking how tightly the components fit before applying the required maximum torque. Do not exceed the maximum torque given by the manufacturer! On parts for which no exact number is stated, start at 2Nm. Always adhere to the numbers stated on the components themselves and/or in the respective manufacturers’ manuals.
If you are not absolutely sure, please ask your STEVENS dealer. Please note the numbers given in the chapter “recommended torque” in your STEVENS quick user guide.

The following maximum permissible overall weight of STEVENS bikes is as follows:
- Allround: 130 kg
- Pedelecs: 140 kg
- Mountain bikes: 115 kg
- Kid's-MTBs und Kid's bikes: 65 kg
- Road bikes: 115 kg
If different, the indication “maximum weight” on the respective model's page (Equipment/Data) applies.
How Frequently Does My Bike Have To Be Maintained?
The degree of wear on your bike mostly depends on the kind and duration of use. The following data are based on an average distance of 1,000 to 2,000km ridded per year. When a bike is frequently ridden on bad roads and/or over longer distances per year service intervals will be shorter accordingly. If you are not absolutely sure or have any questions, contact your STEVENS dealer.

I Would Like To Apply An Anti-Theft Code to My STEVENS Bike - What Do I Need Take Care Of?
In addition to properly locking your bike with a high-quality lock (or even better two locks) in public places, a safety code can help your bike not getting stolen. We recommend applying the anti-theft code by sticker. Etching the code number into your frame can damage your frame beyond repair which will also diminish your bike’s operational safety.
STEVENS Vertriebs GmbH would like to point out that any etching or engraving of the frame – just like any other permanent alteration of the frame – will void warranty!
