UPDATE TO THIS UPDATE: I’ve decided to make steel single-pivot bikes. They are simpler, more ethical,
Sizing, geometry and kinematics have been worked out. Now we shop for fabricators.
We have 5 sizes that perfectly fit riders from 4’10” to 6’8″. We can fit shorter riders with slight compromises.
| Size | Rider height inches |
| M1 | 4’10”-5’2″ |
| M2 | 5’2″-5’7″ |
| M3 | 5’7″-5’11” |
| M4 | 5’11”-6’3″ |
| M5 | 6’3″+ |
Suspension will be a Horst link (a la Specialized, Transition and others) tuned to feel neutral in all situations. The bike will track extremely well on rough climbs and feel like a magic carpet going down.
The first model will be a trail bike (name TBD) in two travel configurations:
- 160mm front / 145mm rear (a bit less for the smallest sizes)
- 180mm front / 160mm rear (a bit less for the smallest sizes)
Wheel sizes are 29 inches in sizes M3 and up. Sizes M1 and M2 get 27.5 wheels, along with slightly less suspension. Fit is so important it trumps wheels and travel.
Another cool thing about this bike
This is the only mountain bike ever designed by a true expert in riding technique and dynamic mountain bike fit (me) and a real-deal chassis engineer (Luis Arraiz from Arraiz Engineering). Luis designed the current GT and Cannondale bike, which are very highly rated. The result will truly fit you perfectly, while it performs at the highest possible level.
Onward!

Have you reached out to Sherwood Gibson of Ventana? I know he was doing work for other companies.
Not yet. Thank you for the suggestion!
I’m really looking forward to seeing all the numbers. I have always been very interested in geometry and on my blog I often advise readers on sizing, using not only my own experience and analysis of anthropometric data, but also the ideas and insights from your book and blog. Seeing all these ideas implemented into a product created from scratch may be (for me) the highlight of the year in the bicycle industry. Seriously.
PS. The height table in centimeters contains a few errors (5’7″ is more like 170 cm, there is also a typo in size M5).

Right on!!
