After changing to drop-bars my rough measurement was 37 x 27.5 x 14 in. The seat-post and stem riser with the drop-bar had to be removed by turning the levers to release and then pulled out before they could be put into a soft travelling bag. A more expensive customisation would be fitted with the seat-post and stem that could be folded without removing from the bike. (See picture: BF folded with detached seat-post and stem riser) Packing: With seat-post, stem riser & wheels removed the bike with all its parts could be packed into a regular-size luggage measuring 31 x 22 x 11 in. without additional charge for oversize luggage imposed by airlines. (See picture: Luggage Bag with BF 1 & 2) What I like about my Pocket Companion: Excellent construction (all BFs are hand-made) of its chromoly carbon steel frame (warranty for life) which is stronger, lighter and more rust-resistant than ordinary steel. I also like its simple design with most components (handle-bar, front & rear derailleurs, shifters, brake, seat-post, stem) that can be upgraded with third-party brands like Shimano & Sram) The monocoque frame is very sturdy and there is no perceptible flexing when ridden. The ride is comparable to that of a regular MTB or road bike (without suspensions). I chose not to have additional joints that allowed the stem riser and seat-post to be folded because each joint added more weight and was more susceptible to vibration giving a "wobbly" ride and the bike tended to shimmy when descending fast down-hill. I have so far ridden the bike for about 120km. and tested it on the Genting-Sempah road in Kuala Lumpur (a long gradual uphill ascend of 25km). I had ridden this road before on my Raleigh Elite MTB and could say that the BF performed just as well without much difference in effort thanks to the 27-speed (the same as that in my MTB). However, the max. speed of descend, without applying brakes, was definitely slower (48km. vs 68km) due to the smaller wheels. The 20in. wheels could climb hills as well as 26in. but again, slower, when pedalling at the same cadence and using both bikes on the lowest gears. What I dislike about it: 1. The Shimano STI Sora shifters was below my expectation. There was a peculiar shifting from the big to the middle chainring when I had to click twice. All the other gear shifting required only one click. The rear derailleur shifting was smooth and easy but not the front derailleur which required me to press harder on the shifter. Perhaps the STI Sora shifter was not completely compatible with the front Shimano Ultegra derailleur. 2. When folding one had to be careful to shift the chain to the smallest chainring and the smallest cog otherwise the tension cable would pull too taut. However, when the chain was in this position (smallest chainring & smallest cog) the chain tended to drop off when the bike was folded. I saw a video which demonstrated how to avoid this but I was not able to keep the chain on which required me to manually reattach the chain after unfolding the bike. 3. Accessories from Bike Friday are very expensive. Furthermore, the authorised oversea dealers do not keep stock. I had to pay a 50% deposit to order a rear folding rack (USD139) and a soft travelling bag (USD79) from the Singapore dealer and was told that delivery would take 2-3 weeks. Conclusion: So far I have enjoyed riding the bike, in spite of its smaller wheels. I shall be using my BF for touring and commuting. The stiff shifting of the front derailleur is something that I can get used to until the Sora shifters wear out and I can upgrade to a better shifter. The foldability is not as easy nor as quick as that of other folding bikes but this wasn't my priority when I decided to buy a folding bike as long as I can pack it into a regular-size luggage bag for overseas travel. Performance, sturdiness, less vibration and less shimmy was what I preferred. In these respects the Pocket Companion passed the test.
