Product Details

Bivi Bikes are, by a long way our most local bike brand, they come from literally round the corner from us and there can’t be many people who’ve specced and built more of them than us .

Bivi bikes are built for serious adventures, using the finest Japanese Sanko steel tubing, fully heat treated to offer 15% more strength whilst keeping the weight low. Subtle reinforcing gussets and intricate cnc finished dropouts make the ride light and lively. They come with all the mounting brackets you need to fully load up and take yourself on any adventure, if I was riding round the world this is the frame I’d want underneath me and without a doubt it would take it in its stride. Their solid build quality makes them excellent for other uses, want a solid commuter that can carry all your gear to work, or how about a great pub bike.
