Yuba: Curry Series

The Spicy Curry Series are Yuba’s lowriders, each designed to keep your rear cargo rack as close to the ground as possible.

It is a simple yet extremely effective solution, paired with a conventional 26″ front wheel Of the many advantages, a low rack is quite a bit easier for your little munchkins to clamber up on by themselves. You have improved stability over a high rear rack too, which works for any cargo you… Read more →

The Ducati E-COM is a terrific place to begin one’s journey with electric bikes and for many, it will be the only bicycle which enjoys regular use.

It’s seat-post-free approach casts aside conventional wisdom, whilst it’s semi-parallel, asymmetric dual-tubing laughs in the face of convention. Beautiful from every angle Then there’s the front fork: two curved tubes swooping from axle to wrist? Check! Grips? Who needs them! Brushed steel Then the drivetrain. Gates belt-drive or chain? You decide! Colours? Any and all. As for the finish: choose from brushed steel to matt or polished paintwork. Matt Black All VIKS are built 100% to order… Read more →

HOPE: District Plus Rear LED Light

The District+ rear light is amongst the brightest lights out there!

At around a dozen times brighter than most conventional options, you can be confident that people behind you can see you as much as 100m in advance. Or further on longer roads, trails and so forth. Note: One thing to be conscious of meanwhile, is that you don’t point it too high at drivers behind you! This is a very bright light and can… Read more →

Damson: Headbones (Bluetooth Bone-Conducting Commuter Headphones)

Music and cycling go together, everyone know’s that! However, heavy commuter traffic can offer up subtle sounds which inform us of the mood of our fellow commuters. This can include simple things like drivers revving their engines and people arguing about traffic/driving/parking/fuel prices inside their cars, or pedestrians yapping on their phones. Difficult to hear when you have your favourite beats going strong! So Damson developed a set of bone-conducting headphones to accommodate this very environment. They press onto your head just in front of your ears and the sounds vibrate towards your eardrums. Your ear canals remain open to… Read more →

Tannus: Aither (puncture-proof, solid bike tyre)

Tired of punctures? You’re not alone! The team over at Tannus have just released the world’s first accessible, puncture-proof tyres. Read the review on The Telegraph here. Formed from a unique polymer with 10 micrometer-wide air bubbles inside a robust mesh of protective walling, the Aither is almost as efficient as a conventional tyre and tube combo. In tests, it managed 29Mph for the effort required of it’s competitor, which reached 30Mph. The test environment assumes that the inflated tyre has the optimum pressure at all times, which of course is where the Aither becomes the tortoise to it’s air-filled… Read more →

Sparse: Fixed Light System (Front/Rear Pair, Plus Charger/Cable)

Every so often we discover a new item which solves far more than it’s initial purpose. Sparse are just one of those magnificent design teams: rather than just add a light to their bikes, they looked at how cyclists really use them throughout the day. Illumination is one aspect, visibility another. Theft however is the unspoken weakness and one, long overdue for solving! Realising that removing/replacing conventional options forms a large part of parking-up, they took a seemingly simple step in making them a semi-permanent fixture. Much like the VANMOOF series of lights, these can be removed if you have… Read more →

Transport

Electric Bikes: It’s not Cheating, it’s Transport A bicycle used for the sole purpose of getting from A-B, is ‘Transport’. Priorities include an upright riding position, day-to-day practicality and suitable pricing. These models are destined to spend a lot of time chained up in public areas. Reliability is crucial and this includes relying on the bike to be wherever you leave it, 100% of the time. The electric bicycle has finally come of age. Battery technology is now truly affordable and ‘Pedelecs’ are a pleasure to go considerable distances on without breaking a sweat. As you pedal, they contribute a… Read more →

City Cycling: Health Versus Hazard? Cities Compared Internationally.

© Sarah Maycock/Handsome Frank http://mosaicscience.com/story/city-cycling-health-versus-hazard Are the fitness benefits of riding your bike worth the risk of an accident? Lesley Evans Ogden takes a tour of seven cities on two wheels to find out. It was just another morning commute. That is, until a bus driver ran a red light, turned right, and drove straight into Ann-Doerthe Hass Jensen. The bus knocked the social worker off her bike, trapping her underneath, a wheel pinning down and crushing her left foot. It was a school bus heading to a Copenhagen kindergarten, and the children aboard were screaming. Ann was rushed to… Read more →

Henry Ford, Thomas Edison and the Cheap EV That Almost Was.

That Henry Ford and Thomas Edison were good friends late in their lives is well-known. They camped together, presented each other with lavish gifts, even owned homes adjacent to each other. Many Ford enthusiasts also know Ford, when he first drove his Quadricycle on the streets of Detroit in 1896, worked for Edison at Detroit Edison Illuminating Company. And historians know Edison, when introduced to Ford some months later and shown Ford’s plans for a gasoline automobile, encouraged the budding industrialist to pursue those plans. What is far less known is Edison and Ford worked together on an affordable electric… Read more →

Thomas Edison & Henry Ford’s Electric Cars

Photograph courtesy Thomas Edison NHP, NPS/DOI. To inventor Thomas Edison in the early 1900s, electric cars looked like the future of transportation. Although better known for inventions such as the light bulb and motion pictures, Edison also designed three electric cars using his nickel-iron Edison Storage Batteries. Here he is seen standing beside a model that left New York on a 1,000-mile promotional “ideal tour” in September 1910, charging along the way and ending with an ascent up New Hampshire’s Mount Washington. By the time Edison’s battery (a longer-lasting, lighter-weight improvement over previous lead-acid batteries) was ready for this journey,… Read more →

Beyond the raw futuristic styling, the Wattbike delivers 200Bhp in near-silence. Yet it’s batteries can be charged to 80% capacity in just 30 minutes (much faster than your phone). 180Km is possible on a single charge too, with a top speed of… Read more →

Mountain Trike

The active chair for active people, the Mountain Trike Offers riders the freedom to venture out around town and into the countryside. Whether that is to the beach, down muddy tracks, over grass or along cobbled streets, gravel driveways and even through snow. We call this All-Terrain. Watch the review on ITV‘s Cycle Show. With a conventional wheelchair, the smallest everyday journey or outdoors activity can seem daunting. The Mountain Trike gives riders the ability to go to places that were completely inaccessible previously, whilst maintaining the function and versatility of a standard wheelchair. Possible applications for the Trike are… Read more →

Electric Bikes: It’s not Cheating, it’s Transport.

Steve McQueen owned the predecessor of our 2012 Pininfarina-designed Velosolex. Before the tyres were even pumped-up on our new ‘pedelec‘, two road racers appeared. One observed that it was electric and the other, that it was cheating… and so began the debate: are electric bicycles ‘cheating’? For those unfamiliar with the term, a pedelec is a bicycle with regular pedals plus a battery and motor. As you pedal, the motor adds a little assistance. When you stop pedalling, the assistance stops. It won’t drive on battery power alone: you have to make the effort to reap the rewards. They don’t… Read more →

Hope: Hoops Pro 3 SP-XC3 (pair)

The Pro 3 SP-XC3 wheelset has been designed specifically with weight saving in mind. To achieve the sort of competitive weights required for racing and performance riding, weight has been taken from the hub and rotor – instead of using fragile, overlight components in the rim and spokes. The resulting wheel is a perfect mix of strength to weight, which has already been taken to many race wins. We suggest a rider weight limit of 85kg. This is only a guideline, but common sense should be used with regards to the type of riding they will be used for. The… Read more →
