Season : 2020

Brand : Whyte


Weight : 20KG

Combining MTB geometry and parts with road bike wheels and tyres has always been the case with Whyte's R-7 line up and the Portobello Hybrid exemplifies this - but the new Plus tyres takes this to a new level. These high-air volume/low-rolling-resistance tyres are perfect for dealing with all surfaces

The Whyte Bikes Portobello features massive 650b x 47c tyres to smooth out the road chatter. These deep profile tyres, give the same rolling diameter as 700c x 28c tyres but the extra air volume make them super comfortable and pinch puncture resistant.

A custom rear dropout mounts the hydraulic disc brake caliper inside the rear triangle, clearing the way for any rack or mudguards that may be required.

Key Features and Benefits

  • A single chainring Shimano Deore gearing setup with super wide ratio gears keeps things simple and efficient for smooth gear shifting and longer service life whilst offering a tremendous range of gears for climbs and decscents too
  • Optimised for hydraulic disc brakes with an inboard mounted rear brake, which gives you powerful easy to modulate braking whilst still allowing you to fit mudguards or a rear carrier
  • Huge WTB Horizon 47c tyres offer a bigger air chamber for increased comfort, improved rolling and resistance to pinch flats from pot holes and kerbs too. And they look cool too!
  • Designed in the UK for the British weather, features such as forward facing seat tube slots, and full outer cable for better sealing, ensure your hybrid will perform rain or shine

Hybrid Bike Sizing Guide

Hybrid bikes as the name suggests are a blend of a road bike and a mountain bike. The fit is a little more precise than a mountain bike, and a little less than a road bike, so you do see a mixture of t-shirt style sizing and measurements in CM and INCHES too. The fit will be more relaxed than a classic road bike though, and is designed to be a little more forgiving and upright.

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'2" 148cm - 158cm X-Small (13 - 14") 33 - 37cm
5'2" - 5'6" 158cm - 168cm Small (15 - 16") 38 - 42cm
5'6" - 5'10" 168cm - 178cm Medium (17 - 18") 43 - 47cm
5'10" - 6'1" 178cm - 185cm Large (19 - 20") 48 - 52cm
6'1" - 6'4" 185cm - 193cm X-Large (21 - 22") 53 - 57cm
6'4" - 6'6" 193cm - 198cm XX-Large (23 - 24") 58 - 61cm

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.
