On-One is a well-known mountain bike (MTB) company, the off-road counterpart to road-bike retailer Planet-X, and this is a bike that blurs the lines between the two brands.
Marketed as an ‘adventure road bike’, this model leans more towards pure road riding with 28mm tyres fitted, but with tyre clearance for up to 40mm that would allow more rugged riding or gravel roads.
The carbon Toray T800 frame will be the stand-out feature for many and it delivers responsive, direct acceleration.

And while the Bish! Bash! Bosh! can’t match more endurance-focused bikes for comfort, it only really struggled on the bigger, sharper-edged bumps.
Another notable feature is the SRAM Apex 1 groupset, with its single 42-tooth chainring that offers a huge range from the 11-42 cassette.
This tech is borrowed from the MTB world and there are many benefits, such as it being simpler and quieter thanks to the clutched rear mech, which also helps the chain stay on without the need for a guide.
Easy up
With a much lower smaller gear than any normal double chainring bike, climbing is a breeze on the Bish! Bash! Bosh!.
The compromise on our test ride was that at higher speeds any slight downhill saw us spin out before we hit top speed, and on the flat we found ourselves using only the smallest two sprockets, with a considerable gap between them.

The Apex shifters are also not the most comfortable to hold when riding on the hoods and the shifting quality can be a little vague at times, a problem that's exacerbated by bar tape that feels thin and doesn’t do much to dampen road noise.
The full hydraulic SRAM Apex brakes, however, are a real plus point, with excellent power and control. The Selcof components get the job done, with the relatively wide handlebar another nod towards more rugged riding intentions.
The bike’s wide, tubeless-ready rims meanwhile are another bonus. Despite the niggles, this is a versatile and fun bike with many great qualities in its favour.

Verdict: While our test bike came with road tyres, the off-road design and versatility of the Bish! Bash! Bosh! is self-evident. With a carbon frame and a spirited ride it’s good on the roads, but with wider wheels would also be perfect for riders who like to wander off the tarmac occasionally.
