Could these “intelligent beads” really revolutionise bike design? Plus more tech news from Michelin, Wahoo, Cannondale, Cafe du Cycliste and loads more

The bike world is super busy now we’ve hit summer and we have news to tell you about from Michelin, Wahoo and Cannondale, along with a really neat tool that’s flying on Kickstarter, but we’re starting with a drive system that ditches the conventional chain in favour of intelligent beads. Yep, that’s right, intelligent beads…

Could this revolutionary drive system really transform the cycle industry?

A British inventor plans to revolutionise the cycle industry with a system that uses “intelligent beads” housed in a cassette to provide two-wheel drive rather than a conventional chain – that’s “cassette” in the sense of an enclosed container rather than a cluster of sprockets. David Jephcott’s Injenius bike also uses internal braking and smart gears.

The University of Sheffield’s Advanced Product Development Centre has described the design as “the most exciting development in cycling history since the turn of the last century, incorporating a revolutionary drive system that could transform the industry” although a prototype has yet to be built so we can’t show you pictures of it in action.

Gerry Wilkinson, who is working with David Jephcott to deliver the project, says, “The Injenius bike works with an intelligent compression drive which distributes the energy to both the front and rear wheel equally purely by a more efficient use of human effort via the pedals.

“The design brings all the advantages without the potential of electronics being compromised in the middle of nowhere and leaving the bike unrideable.

“We can add a motor to the pedal mounting should it be needed but this will only be an aid as and when required and without affecting the main principle of the design.”

David Jephcott says, “Having proven the concept via a physical drive cassette and CAD (computer aided design) simulation, we are now adding the front wheel drive and powered steering to provide greater stability on greasy surfaces and increased safety via improved handling.

“Our first fully equipped prototype will be a road bike version. This process will determine the parameters within which the drive will work most efficiently.”

“We aim to achieve 1% of the global market within three years by initially licensing the technology to manufacturers who already have market share plus manufacturing and distribution channels in place.”

The Injenius bike has no chain to slip, break, or get dirty, and David promises it’ll be low maintenance along offer improved traction.

David Jephcott has a long history of working on related ideas and patented a method for transferring drive using “a line of contiguous bead-like drive-transferring members” way back in 2002. You can check out the design here. 

There are already chainless bike designs out there but they’ve never hit the mainstream. CeramicSpeed demonstrated its shaft drive concept, called Driven, back in 2018 and a year later demonstrated that it could change gears thanks to some electronic trickery.

The design uses a shaft tipped with CeramicSpeed’s ceramic ball bearings to drive the rear wheel instead of a chain, with the brand claiming this is part of its effort to create a 99% efficient drivetrain. Clever engineering, but it has never come to market.

Various people have tried to create two-wheel drive bikes – Japan’s Double showed off its 2 WD system back in 2017, for example, and Christini offers a range of two-wheel drive models.  Again, though, the concept hasn’t seen widespread adoption.

As mentioned, the team behind Injenius says that the two-wheel drive nature of the design improves traction but it also plans to offer a single-wheel drive version that can be retrofitted to an existing bike.

What do you think: is Injenius the next big thing or an answer in search of a problem? Let us know in the comments.

Michelin introduces new Power Adventure tyre

Michelin has introduced a Power Adventure off-road tyre that features a hybrid tread design to roll well on and off tarmac. Michelin says it's aimed at cyclists who ride about a fifth of their time on rougher gravel or dirt roads – which seems quite specific, but we get the idea.

> Best road bike tyres 2023 — ride faster and further with fewer punctures

There are two colours available: black or classic, which Michelin says can “match and enhance” your bike. 

The tyre uses a new rubber compound, Michelin Gum-X Technology, that is said to be optimised for grip on both dry and wet surfaces. It comes with a lightweight 3x100 TPI construction with a bead to bead technology – an additional protective layer surrounding the entire carcass for better puncture resistance. 

The Michelin Power Adventure is available now in 30, 36, 42 and 48mm widths and each tyre costs £54.99.

MetMo Pocket Driver multitool destroys Kickstarter funding target

The MetMo Pocket Driver multi-tool isn’t bike-specific but it’s certainly bike-relevant and it has currently received pledges totalling £900,000 more than its Kickstarter funding target with over a fortnight remaining.

The Pocket Driver is a smaller version of the original MetMo Driver that raised well over £1 million via crowdfunding.

It’s designed to be “a compact hybrid between a T-handle and ratchet drive”.

“With its impressive torque, this tool serves as a versatile screwdriver, a compact T driver, and a substitute for Allen keys, while remaining agile enough to be used as a micro driver,” says MetMo.

It’s a full-metal construction and takes standard 1/4in (6.3mm) hex heads. You can store two inside.

You need to pledge at least £89 to be in line for a MetMo Pocket Driver with delivery expected in February 2024. Pledging money on crowdfunding sites is not the same as buying through a retailer.

How do pro teams keep track of their tubeless sealant?

If you use sealant inside tubeless tyres you’ll know that you need to add some extra from time to time because it gradually dries out. It’s easy enough to remember when you last topped up if you only have one or two bikes, but what if you look after wheels for a whole pro team?

This is a wheel/tyre from the bike of Tour de France champ Jonas Vingegaard that we saw at the Criterium du Dauphine last weekend. One of the mechanics has written 24.05 – 24th May – on there with a Sharpie. It's a simple method that's used by most of the pro teams.

Teravail launches Telegraph, its first-ever road tyre

Teravail, a brand well known for its gravel tyres, has launched its first-ever road tyre called the Telegraph. The new tyre is said to combine “high-speed grip and comfortable compliance to provide riders with a modern road experience”. 

The Telegraph is built with 120 TPI tubeless-ready casing with a single-compound rubber chosen for its compliance and grip. It also features a textured tread cap that should further increase grip on the tarmac. 

For puncture protection and better tubeless performance, Teravail has added an internal liner, and the tyre is available in Teravail’s Light and Supple casing or a new road-specific Durable casing.  

The Telegraph tyre is available in single 700c x 30mm size but in three casing and sidewall combos: 

Black Sidewall with Light and Supple casing £45
Black Sidewall with Durable casing £48
Tan Sidewall with Light and Supple casing £45

We've requested some for review on road.cc.

A cup of Joe on the go: Restrap introduces portable coffee dripper

We all know that coffee and cycling go together like bacon and eggs, strawberries and cream or Thelma and Louise, so it’s no surprise that British bikepacking specialist Restrap has introduced a portable coffee dripper.

Restrap initially introduced the product for a limited time last Christmas and it was so popular that it has been brought back as a permanent addition to the range.

“Three shaped pieces lock together to allow a V60 filter to sit above your mug, using a specially designed shape that always sits centrally and securely while your favourite brew drips through,” says Restrap.

When you’re done, it packs into its own textured nylon pouch. The Restrap coffee dripper is yours for £9.99.
