Amity Components
"High end components at reasonable prices" a simple ethos but one that leads most brands down the road to expensive low volume manufacturing. Stomp were determined not to fall down the same trap.
This was a group of several projects all aiming to produce multiple variants. The majority would get a stock finish and would be sold on complete bikes allowing bike costs to be reduced and boosting production numbers over the threshold needed to justify tooling . Others would recieve futher processing/machining and get a higher end finish, these would be sold separately in lower quantities to grow the offering and brand image of Amity Bike Co.

S1 and S1-Pro Stem
Early on it was established that the most cost effective approach would be to design a forged stem for use on complete bikes. This forged stem would then be CNC machined over the majority of it's surfaces and anodised to create the higher end aftermarket stem. This approach tied both designs together and created a fine balance when differentiating the 2 designs. Several concepts were quickly refined 3D printed and narrowed down to a single design. This was then CNC machined for several samples and tested.
F1 Saddle
This saddle is made up of 6 parts, the rail and cover were relatively straight forward requiring only some graphic design. Meanwhile the foam, substrate and 2 trim pieces were all designed from scratch to have their own injection moulding tools. The strength and weight requirements of this seat made the design of these moulds very challenging but the soft tooled prototypes exceeded our expectations.
Lagos Grips
There are currently only 2 brands offering lock-on grips wider than 120mm. This design for a 130mm dual lock-on grip would be the only one available outside of the USA and would be a huge hit among UK freestyle riders.
Several designs were considered and printed with a soft compound on a polyjet printer before being refined for production.
B1 and B2 Handlebars
These handlebars were both designed primarily for use on full build bikes in order to keep there initial quantity's high enough to warrant their expensive tooling. These would also not be butted in order to reduce cost on these "stock" bars. The hard part was to design the external shape in a way that would still work for a butted variation of the bar to be made with the same tooling later on. This was assessed using FEA to confirm that the required butting positions were not too far out resulting in an aftermarket bar that would be too heavy.
