The back fork should be connected to the seatpost with a pair of horizontal braces.
It's an exaggeration to say it would immediately break. But if you put weight on it, it will tend to spread out (imagine putting weight on a bent piece of metal shaped like a ^). Still, the front fork isn't braced, and bikes exist with quite a large rake angle on the front fork (think a Harley-Davidson style chopper). So maybe you can make this design strong enough to bear a person's weight.
- dTal 7y agoAs it's a single speed with no derailleur and the missing braces would be in tension, might not the chain itself fulfill the role?
- bsmith 7y agoIt could, but undue tension on the chain vastly decreases the efficiency and longevity of the chain, and potentially, the cog/chainwheel. This would also present a safety issue because chains can (and do) break.
