Self supporting chassis of Twintex Print

versatile-open01For the self supporting chassis we are using Twintex, a continuous fibre reinforced thermoplastic material. Twintex has a glass to weight percentage of 65%. The fibres are a hybrid mix of continuous glass filaments combined with continuous thermoplastic filaments (PP polypropylene) with on average the same diameters. Because of the subtle, homogeneous distribution of filaments within the Twintex material, one can make composite products with very short cycle times and relatively low pressures without compromising the consistency of the mechanical properties. The mechanical properties of Twintex with PP are similar to Polyester with high glass to weight percentages, just with one exception …………. The impact resistance and wear resistance of Twintex are much better. Also the chemical resistance and especially the moisture resistance of Twintex are very good.

 

 

 

 

 

 

 

 

 

Common advantages of Twintex:

 

  • Very high hardness, impact resistance and wear resistance
  • Not sensitive to resonance
  • Can be recycled
  • Low emission and ecologically sound
  • Excellent moisture resistance

 

Rohloff hub, speedhub and reducer at the same time


 

The distinguished Rohloff speedhub is a state of the art piece of technology which perfectly blends in with the high tech Versatile. The Versatile requires a maintenance free and idiot proof drive train system with large gear ratio, high efficiency, the possibility of shifting during stand still, easy operation, light actuation and of course a long lifespan. Within the Versatile the Rohloff speedhub functions as a gear box with equal steps between the gears. Each step means a 13.6% increase, therefore the 14 speeds in the Rohloff speedhub offer a gear ratio of 526%. Similar to the gear ratio of a 27 speed derailleur drive train, but without the disadvantages of a derailleur drive train. Besides, when taking into consideration the traditional overlap of gears and the way the chain is running, a regular 27 speed derailleur drive train effectively only has 15 efficient gears. The Rohloff speed hub has only one disadvantage: a relatively high purchase price. Nevertheless, the return on investment is high; the hub can be used for many years without maintenance or replacement of spare parts!

Safety


We paid a lot of attention to the rider’s safety of the Versatile. To further increase the visibility of the Versatile the two contrasting colours of the bodywork can be equipped with additional reflective material. The chassis framework has a roll bar and further reinforcements around the rider’s seat. The two rear mirrors belong to the standard equipment. Next to the standard battery pack a 2nd head light can be switched on and on the front and the rear side indicators are being installed. The Versatile has a segregated braking system on the front wheels; each brake lever brakes both the left hand and the right hand front wheel independently. The brake on the rear wheel is a hand brake only for parking.
