|The GreenSpeed Aunra is designed for riders who may have problems getting in and out of the low seats on most tadpole (two front wheels, one rear wheel) trikes. The seat on the Anura is as high or higher than most kitchen chairs, at 18” from the ground, plus there is no cross member in front of the seat, or wheels to the side. Thus it is very easy to mount and dismount.||It is also designed to be used in tandem format, so that by removing the front wheel of one trike, the rear trike can be coupled to the front trike. Thus people with serious health issues, who want to cycle, but fear they do not have the strength or endurance, can cycle with their partners, and put in as little or as much effort as they want. In fact many people with serious illnesses like MS have made miraculous improvements in their lives, through getting regular exercise on the Anura.|
Performance Superior Traction
The frame of the Anura is 7005 aluminium alloy, and it has a simple design, so it is quite a light trike for a delta design. While the more upright seat will make it slower than some tadpole trikes with the low angle seat, the Anura has far superior traction. This is because instead of having only 1/3 of its weight on the single driving wheel on tadpole trikes, the Anura has TWO driving wheels with ¾ of the weight on them. Thus with the Anura you can ride up steep hills where there is gravel without the rear wheels spinning. It is also superior to other delta trikes which only have one wheel drive, in which the front wheel will tend to crab across the road, on steep hills. In fact, you can even ride the Anura on snow!
Another feature of the Anura is the narrow track. This allows the Anura to be ridden between bollards with confidence, and in fact at only 28.5” wide, it can be ridden through a standard doorway. Locating the seat close to the driving and balancing wheels give more stability than would be expected, and if more stability is wanted with the narrow track, then there is the Anura Quad which has more stability than most tadpole trikes. The rectangular main tube keeps the front frame in perfect alignment with the rear frame, making leg adjustment quick and easy with the optional Chain Gobbler, and is stronger than the round tube used on other trikes.
Smooth Changing Gearing
The Anura offers a choice of gearing systems. The Anura RL has the conventional 27 speed derailleur system with a triple chainring and crankset, and nine speed rear cassette. However, the Anura IGH offers the increasingly popular Nu Vinci infinitely variable ratio hub. This has a number of advantages over the old chain derailing systems. It has a gear range of 380%, from 0.5 in bottom to 1.9 in top. There is no clunk or jerk as the gears are changed, there is just a very smooth change in gear ratio as you twist the shifter, from low to high or from high to low.
As there are no steps in the system, there is no such thing as having one gear too low and the next too high, you can choose the ratio which is exactly right for whatever you are doing. Plus, without any internal gears nor ratchets, the hub is completely silent. At the front of the IGH is a ATS Speed Drive – a two speed bottom bracket, which increase the gear range to 627%. If need be, this can be replaced with a Mountain Drive, giving a gear range of 950%. Yet another advantage of the Nu Vinci system is that you change through over 50% of the range while stationary. So if you have to stop suddenly and do not have time to change down, you are able to change down far enough to take off OK while stopped.
One thing we have found with some children is they find it so relaxing sitting in the recumbent position that they can forget about keeping their feet up. (warm sun, relaxed and birds singing, it’s not un-heard-of to find a young one asleep at the wheel.)
There is a fairly simple and virtually pain free solution, which is to have simple pedal straps. You can also use bicycle cleated shoes and special receptive pedals – but this can be a little more expensive as young feet tend to grow quickly. Simpler to use shoes you already have as the straps are adjustable to many different shoe sizes.
