The Sigma must surely be one of the lowest step-through folding electric bikes available on the market today. Manufactured in Europe to all the latest quality standards the Sigma inspires confidence. The low step-through frame makes it very easy to mount yet the frame colours and graphics give the bike style and panache.
The Sigma is fitted with Shimano Nexus 7 speed hub gears that are easily selected with the Nexus twist grip gear changer. Battery and assistance levels are readily seen and controlled from the handlebar mounted display.
The Sigma can easily be folded for storage making it ideal for motorhomes and leisure riders or for those with limited space at home. When folded the hub gears mean that the chain is kept neatly tucked away.
Liveried in a choice of one of three Batribike colours of Hunter Green, Earth Brown or White Shadow, the Sigma has colour matched mudguards and forks. The gold Jupiter Metallic chain guard and graphics compliment the frame colour, along with matching seat and grips, and quality Schwalbe tyres. This creates a very well presented folding electric bike.
