Mtb Zebra S.H.B. : "Sleek Hardtail Bike"

Concept of a sleek hardtail MTB, but fully capable, still with a gearbox but with a chain this time, not a carbon belt.

I wasn't much inspired for the name, I hope you'll find me more inspired for the bike :)

Alloy frame, straight tubes, gearbox, 140-160mm fork, 29 front, 27.5+ rear, AM/Enduro hardtail.

Don't get misled by the tire label, this is not an e-bike, it's just that this front e-bike tire seemed like a good rolling/resistance/weight compromise at the rear.

The rear brake cable runs along the toptube and seatstay to prevent bubble trap as much as possible.

Streamlined dropouts, a big disk and some nice hardware. I considered asymetric chainstays at some point but decided against it in favour of tire clearance.

That half-link chain looks cool but would be swapped for a regular chain on a real bike, probably with a chain tensioner near the gearbox.

The gearbox's preload spring black tube is hidden underneath the chainstay protection. With a bit more development maybe it could be integrated inside the chainstay.

Some fancy (and expensive) Bike Ahead biTurboE e-bike carbon wheels that would hopefully withstand the all-mountain/enduro program of the bike, but some alloy rims are probably better for a hardtail.

The drive sprocket protrudes at about 15mm so I decided to offset the gearbox on the left by half as much, to bring the chainline as close as possible (while still allowing 3.0" wide tires). I don't know if it would cause structural problems though.

Plenty of space for a large bottle on a hardtail, even with a fair amount of sloping.

With such sloping and chainstays the rear triangle is more acute than most bikes, I don't know how it would affect the bike's behaviour and solidity.

The geometry is in fact quite similar to my previous hardtail, the JSB.

A black reflective background was not the best idea.

If you think the bike looks too much like an XC bike with the 6 spokes carbon wheels, here it is with standard laced wheels.

Duke's Fury Jack are carbon rims though, so still not what you'd want to use with a stiff alu frame, but they look cool.

Bonus picture : You may have seen this shock already if you follow me on Instagram, and while this bike doesn't need one, it looks rad so here's a render.

Bonus picture 2 : You may have seen it on Instagram as well, I couldn't resist doing this quick photoshop of how the bike looks with the straight tubes (and wheels) shrunk as much as possible. Till next time !
