The frame is equipped with our updated Zero Suspension, offering 165 mm of rear travel and Forward Geometry specifically tuned for this lightweight, long-travel e-bike.

DUNE R: THE ENTRY LEVEL BUILD

The DUNE R is the gateway to the world of DUNE. A 170mm FOX 38 Float 3P Performance Grip fork keeps the front wheel in check, whilst a Fox Float X Performance EVOL shock does the job at the rear. SRAM supplies the GX Eagle rear derailleur and e*thirteen its E*Spec Plus crankset, ONOFF the Pija dropper post, SRAM the DB8 brakes, and e*thirteen Grappler Core wheels with 30mm-wide aluminium rims round the whole thing off.

Safety information for bicycles, e-bikes and children’s bikes

Safe and long-term use of bicycles, e-bikes and children’s bikes requires careful checks, regular maintenance and proper handling. These guidelines provide practical recommendations for safe use and should be followed in conjunction with the manufacturer’s operating instructions.



1. Safety checks before riding

The following checks should be carried out before every ride :

Brakes and steering : Test that the brakes are working properly and ensure that the steering is smooth and stable.

Tyres and wheels : Check that the tyre pressure is correct and that the wheels and quick-release skewers are securely fastened.

Fittings : Check that attachments such as mudguards, luggage racks, saddles and pedals are securely fastened.

Accessories and loading : Ensure that luggage and accessories are correctly fitted and that the maximum load capacity is not exceeded.



2. Technical safety and permitted use

Component inspection: Regularly check safety-critical components such as the frame, fork, handlebars, seat post and brakes for damage. Do not use the bicycle if there are any visible defects.

Maximum load capacity : Observe the weight restrictions for the total weight (bicycle, rider, load and, if applicable, trailer). You will find the specifications in the manufacturer’s information.

Proper use : Only use the bicycle or e-bike within the intended category of use. Improper use leads to safety risks.

Accessories and modifications : Only use approved accessories such as child seats or trailers, and do not make any unauthorised modifications, particularly to the drive system of e-bikes.



3. Special notes for e-bikes

Battery and charging:

Only use batteries and chargers approved by the manufacturer.

Charge the battery in safe locations and in accordance with the temperature specifications.

Remove the battery before transporting the e-bike.

Electric assistance:

Familiarise yourself with the assistance modes and the push assist. Test the e-bike first in a safe environment, particularly with varying loads or difficult ground conditions.

Running-in disc brakes:

Run in new brakes before your first long ride to ensure optimum braking performance.

Transport guidelines:

When transporting the bike, follow the manufacturer’s instructions and comply with legal regulations.

Component manuals:

4. Special safety rules for children’s bicycles

Duty of supervision: Children must only use bicycles under the supervision of a responsible adult.

Suitable size and equipment : Ensure that the bicycle is age-appropriate and that all safety features (e.g. brakes, reflectors, chain guard) are in good working order.

Loading and accessories : Securely attach child seats and luggage racks and ensure that the load capacity is not exceeded.



5. Care and maintenance

Cleaning : Use a soft cloth and mild cleaning agents. Avoid high-pressure washers to prevent damage to electrical and mechanical components.

Regular inspections : Schedule regular maintenance with a qualified specialist to check for wear and tear and ensure safety.

Spare parts : Use only original or approved spare parts to maintain the functionality of the bicycle.



6. What to do after your ride

Document any damage : If there is any visible damage or malfunction, the bicycle must not be used any further. Have it checked by a specialist workshop.

Avoid hot components : Avoid contact with heated components such as brake discs or drive units to prevent burns.



Final notes

This safety information provides you with a comprehensive overview of the safe use of bicycles, e-bikes and children’s bikes. Always follow the manufacturer’s instructions for use and contact a specialist dealer if you have any questions. Safe and responsible use not only ensures your safety but also extends the life of your bicycle.
