The time has come. Your first experience on your own Orthros! Whatever bike ride you do, your safety comes first! If it is your first time cycling on a Huka companion cycle, you may have to get used to it. The most important tip we can give you is that you should relax as much as possible while cycling.
• Wear an appropriate bicycle helmet. • Wear reflective clothing to increase visibility on the road. • When the Orthros is used by children or young people, we recommend never letting small children ride alone in public traffic. • Before setting off, check that the lights are working and replace the batteries on time.
This reduces the risk of falling. Pedal assisted bicycles If your Orthros is equipped with pedal assistance, the electric motor is activated as soon as you start pedalling. Pedalling then becomes lighter. If you stop pedalling, the pedalling assistance stops as well.
Control buttons Battery indication If your Orthros is equipped with pedal assistance, the display will indicate how full the battery is. Check whether the battery is full when you (longer) distances. The black block gets shorter as the battery gets emptier.
Product description Your Orthros consists of several parts. The most important parts are described in this chapter. Bicycle frame The Orthros frame consists of a tubular metal construction complemented by aluminium and stainless steel components. Most of the metal parts have been phosphated and then given an impact-resistant powder coating.
Huka dealer. Brakes The basic model of the Orthros has V-brake in the front wheel and disc brakes on the rear wheels. These brakes are operated by the driver of the bike by means of brake levers on the handlebars. An extra back-pedal brake that operates the rear wheels is optional.
• Various (modified) pedals are available as an option. Gears Your Orthros is equipped with gears, whereby the gear hub is located between the pedals and the drive shaft. This is an 8-speed Nexus hub from Shimano, which has been tuned to the Orthros. The duobike can also be delivered in combination with an automatic reverse gear (reverse cycling is also possible).
Luggage basket As an option a luggage basket can be mounted on the back. Ask your Huka dealer about this, so that the right materials can be used and the whole thing can be assembled safely.
Electric pedal assistance The Orthros can be equipped with electrical pedal assistance. This means that the double bike has an electric motor in the front wheel, a battery pack and an electronic box on the middle frame tube.
Accessoires Your Orthros can be expanded with various accessories. Think of armrests, luggage basket, foot box, cane holders etc. More about these options can be found on the price list on our website www.huka.nl/en or contact your Huka dealer. Switchable freewheel...
Optimal use When you receive your new Huka, the parts have been adjusted to your body and to your wishes. To make sure you are comfortable, there are adjustment possibilities for the seat system and handlebars. Adjust the seat depth To adjust the seat depth, the following actions apply: 1.
Make sure that the stem retains enough of its position in the frame so that the MIN'' safety marking is not visible. 3. Tighten the handlebar bolt securely again according to the Tighten the handlebar bolt again properly according to the described tightening torque on page 17. www.huka.nl/en...
Adjust steering height 1. Using a size 5 Allen wrench, loosen the stem bolt slightly by a few turns then give a little tick on the allen wrench to allow the handlebar to slide. 2. Pull or push the handlebar to the desired height. 3.
Always inflate the tyres properly. This prevents wear and tear on the tyres of your Orthros. It is also a more pleasant ride and you can react better to braking and steering movements. The correct tyre pressure is reached when you can press the tyre with your thumb.
Regularly check the tyre pressure and tyre profile for optimum grip on the road. The Orthros can be inflated with a normal bicycle pump. The recommended tyre pressure is 4 bar. After inflating check that the valve does not leak. To do this, smear some saliva over the valve tube.
Bonding Have you discovered that one of your Orthros' tyres has a flat tyre? Your Huka dealer can of course fix it. But if you want to do it yourself, here are the instructions: You will need: a repair kit (with tyre levers, glue, stickers and sandpaper), a jack, scissors, a bicycle pump and a bucket of water.
Can't you adjust the brakes or does the Orthros still not brake well? Then have it checked and adjusted by your Huka dealer.
