Overall Rating: (5/5) Highly Recommended
We are very excited to use our BikeBuddy’s to securely mount ½ gallon bottles on our frames and also to carry up to 1.0 liter (33oz) fuel bottles underneath the down tubes on our bikes without any fear of vibrations and road shock dislodging any of them.
The MK3 “quick release” version (as shown in photo to left) works as so:
The spring-loaded carrier is wrapped around the bottle and then the whole assembly is mounted via tapered keyholes (friction) to a couple of tapered bolts screwed into the water bottle bosses. Friction resulting from the two tapered surfaces (of the bottle carrier and the studs) contacting each other hold everything firmly in place – a truly elegant solution. The carrier is never removed from the bottle – the whole assembly (bottle and carrier) comes off – so the only things left on the bike when the bottle is removed are the two small studs. BikeBuddy’s are available in two other versions but we think the MK3 is the ultimate expression of the design.
One note for anyone interested in utilizing the BikeBuddy carrying system: the particular combination of the size of your frame, the unique placement/position of your water bottle bosses and the size/shape of the container(s) you wish to carry must be factored together prior to purchase. The reason for this is that although the BikeBuddy system itself is quite versatile, in that it can be inherently modified to fit lots of different setups, there are limitations.
For instance, you can see from the image below of Kai’s setup, that he utilizes two BikeBuddy’s – one mounted on the topside of his down tube and the other underneath. The placement of his bike’s bosses so low in the main triangle limits the practicality of a third BikeBuddy mounted on the “leading edge” of the seat tube. Of course, this works for Kai since he wants the ability to drink from a bottle while cycling and so he has installed a Klean Kanteen cage in this position (to house a .80L (27oz) Klean Kanteen). This combination – one 1.9L (64oz) bottle and one .80L (27oz) ounce water bottle – essentially “maxes-out” the storage capability inside his bike’s main triangle since the large diameter of the 1.9L (64oz) bottle does not permit a bottle bigger than 27oz to mounted on the seat tube, no matter how the BikeBuddy’s are positioned/installed. Since there are all kinds of options for cages to fit 27oz or smaller bottles there is no real reason to install a third BikeBuddy, particularly since the BikeBuddy system is not designed to allow the cyclist while in motion to drink from a bottle carried in a BikeBuddy.
However, just the ability to safely secure such a large bottle on the frame makes the BikeBuddy more than worth while. Utilizing the BikeBuddy’s, we can each safely carry 2.7 liters of potable water (91oz total) and up to 1.0 liters (33oz) of fuel utilizing just the three sets of conventional water bottle bosses. Of course, allowances could be made during a custom frame building process vis a vis placement of the bosses or one could make use of the clamp-on MK1 version to allow even higher capacity storage/transport within the confines of frame of a bicycle.
