Bike bag

The order was prompt on delivery, absolutely worth every penny and I am very pleased with my purchase. I revieved puncture scabs too which was a lovely gesture and I highly recommend the company and will shop there again definitely.

Bike cross bar bag

Bicycle Bag

A great purchase for me. I was uncertain it would sit securely to my "egg" shaped cross bar so I posed the question which was answered positively very quickly. The longer strap for the handlebar stem and the two underneath straps combine to a provide secure fitment. A versatile bit of kit which is great value for money. Strongly recommended.

Practical handlebar bag

This is my second order, as I was very pleased with the first. I purchased the large BTR Bike Phone Holder Bike Bag, rather then the medium. It easily takes my iPhone 5 plus a battery back-up and lead, a few allen keys and other small items. The touchscreen operates fairly well through the transparent cover. The bag is rugged and waterproof enough even without the cover, although the cover will me useful in heavy rain. The bag is stable on the bike. A very good value product as well.
