Greetings Bicycle Enthusiasts,
With an introduction of new products into any market there may be some resistance to acceptance in the form of skepticism or cynicism. At Abio, we thought we would create a Cole’s notes to highlight some of the features of our chainless folding bikes.
Quick Release Levers 
The point of our quick release levers is exactly as the name describes. The function of the levers is to create a quick firm seal around the folding hinge to prevent wobble in the main body and handle bar stem during riding. As an ancillary to the quick release levers, the folding joints from the main body and handle bar stem have locking mechanisms that prevent the bikes from unraveling during transport in fold position.
Internal Gear Hub 
We have to thank the evolution of the internal geared hub for helping to blossom both the shaft and belt drive mechanisms. The relatively maintenance free system uses a set of planetary gears that rotates about a stationary sun gear. The bottom line – the internal hub provides a range of gearing options that is fully enclosed and compact. More on the system can be found here:

Shaft Drive 
If you can believe it shaft drives have been introduced over a century ago. The shaft drive system uses a combination of precision beveled gears to translate rotational motion to linear motion on the rod or shaft. The spinning shaft then transfers motion back to another set of beveled gears to propel the rear wheels. The result is that you have a drive system that is entirely enclosed. The shaft drive is safe for all pants from getting caught on moving parts or grease. Let’s not forget to mention you look pretty chic too.
Belt Drive 
The belt drive is much simpler to conceptualize. It looks like your conventional chain assembly but instead uses a belt made of synthetic materials developed by Gates. The Gates belt is highly durable and is used in many industrial applications with much more demanding requirements than a leisure bike ride. Since our belt drives are mated with internal gearing system you get a truly greasless system.
Nexus 3sp and 4sp 
When people hear that Abio Bike’s are equipped with 3, 4sp gears, they may be reluctant that it will meet their riding needs. We want to point out that yes it is a 3,4sp set up but the gears are spaced wider apart. In other words, the gearing jumps are greater when going from gear 1 to 2. This allows Abio’s 3,4sp gears to cover a similar gearing range as say a 7 or 8sp bike.
