The super enduro of lightweight e-bikes
The DUNE is based on a Stealth Air carbon frame weighing 2650 grams, combined with the power and low weight of the latest Bosch Performance SX. The frame is equipped with our updated Zero Suspension and offers 165 mm of rear wheel travel and a Forward Geometry specifically designed for this lightweight, long travel e-bike.
DUNE R: THE ENTRY LEVEL BUILD
The DUNE R is the entry level build into the world of DUNE. A 170mm FOX 38 Float 3P Performance Grip fork keeps the front wheel in check, while a Fox Float X Performance EVOL shock does its job at the rear. SRAM supplies the GX Eagle rear derailleur and E.13 its E*Spec Plus cranks, ONOFF the Pija dropper post, SRAM the DB8 brakes and e*thirteen Grappler Core wheels with 30 mm wide aluminium rims round off the whole thing.
This bike arrives (almost) fully assembled. All you have to do is straighten the handlebars and attach the pedals.

Safety information for bicycles, e-bikes and children's bicycles
The safe and long-term use of bicycles, e-bikes and children's bicycles requires careful checks, regular maintenance and proper handling. These instructions provide you with practical recommendations for safe use and should be taken into account in conjunction with the operating instructions of the respective manufacturer.
1. Safety checks before riding
The following checks should be carried out before every journey:
Brakes and steering: Test the functionality of the brakes and ensure that the steering is smooth and stable.
Tyres and wheels: Check that the tyres are correctly inflated and that the wheels and quick-release skewers are secure.
Fastenings: Check that attachments such as mudguards, pannier racks, saddle and pedals are securely fastened.
Accessories and load: Make sure that luggage and accessories are correctly fitted and that the permitted load capacity is not exceeded.
2. Technical safety and authorised use
Component inspection: Regularly inspect safety-relevant components such as the frame, fork, handlebars, seat post and brakes for damage. Do not use the bike if there are visible defects.
Maximum load capacity: Observe the weight limits for the total weight (bike, rider, payload and trailer, if applicable). The details can be found in the manufacturer's information.
Proper use: Only use the bike or e-bike within the scope of the intended use category. 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, especially to the drive system of e-bikes.
3. Special instructions for e-bikes
Battery and charging process:
Only use batteries and chargers approved by the manufacturer.
Charge the battery in a safe place 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 pushing aid. Test the e-bike in a safe environment first, especially with different loads or difficult ground conditions.
Running in the disc brakes:
Run in new brakes before your first big ride to ensure optimum braking performance.
Transport specifications:
Observe the manufacturer's instructions and legal regulations when transporting.

Appropriate size and equipment: Make sure that the bike is age-appropriate and that all safety devices (e.g. brakes, reflectors, chain guard) are intact.
Loading and accessories: Attach child seats and pannier racks securely 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 cleaners to prevent damage to electrical and mechanical components.
Regular inspections: Schedule regular maintenance at a qualified specialist company to check for wear and ensure safety.
Spare parts: Only use original or approved spare parts to maintain the functionality of the bike.
6. Behaviour after the ride
Documenting damage: In the event of recognisable damage or malfunctions, the bike must not be used any further. Have it checked by a specialised company.
Avoid hot components: Avoid contact with heated components such as brake discs or drive units to prevent burns.
