Welcome to the GCN Tech Show. This week we’ve got electric commuter bikes with their own names like Adam and Hannah, tyre trimming, some very nice bikes that belong to you, plus our talking point - what happened to graphene?

Schindelhauer is launching 4 urban e-bikes at the start of 2019. The names of the bikes are people's names so there is nothing fancy here! We’ve got Adam with a MAHLE rear hub motor, and Karl, Heinrich and Hannah all use Bosch mid frame motors. Hannah incidentally will have a step-through frame design. Plus Karl will be the world's first single speed bike with a Bosch motor!
Graphene can be described as a single layer of graphite. It was discovered by two Russian scientists Andre Geim and Konstantin Novoselov at the University of Manchester It’s an allotrope of carbon, other allotropes include diamond, coal, buckminsterfullerene and carbon nanotubes.
Although some products claim to feature graphene its important to understand it isn’t in a large scale sheet, as our imagination may suggest. They aren’t built from graphene in the traditional sense. Most commercially available graphene looks like a black powder and it is small amounts of this black powder that are incorporated into the carbon fibre resin in the case of Dassi or rubber compound in the case of Vittoria Corsa G+. What we have therefore is composite materials, that contain graphene.
What applications would you like to see graphene used for? Let us know in the comments. 👇
