Bought one to replace the dead weight bike on the right. That one was 99p on eBay, loads of choice of similar bikes for that money. When the islabike arrived I thought it felt a bit heavy, just weighed them. The islakibe is slightly heavier. My own fault, their website does state they're 7.7kg.
That's nearly 18lbs. The frame is aluminum, the wheels, forks and bars must be practically solid. They have the short levers but they're only £7 on CRC. Gear ratios are the same. I'm really not certain where the money goes.
