The bay has a number of options as well: add the ‘rail & sail’, or bamboo box, as well as a pair of bamboo seats. Any cargo which can be strapped down securely… Read more →

The Spicy Curry Series are Yuba’s lowriders, each designed to keep your rear cargo rack as close to the ground as possible. To achieve this, they tuck a 20″ wheel akin to a tough BMX bike’s wheel way back and below the height of the pedal stroke. 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 MiRider GB3 is the hotly celebrated geared model in the line-up, upgrading the One to a Gearbox system with belt drive and hydraulic brakes. “The GB3 features a sophisticated crank-based gearbox system with a belt drive which allows the hub motor to stay at the rear, retaining excellent weight distribution, balance and the traction of the standard bike, without the adjustment issues of a traditional derailleur. The GB3 also benefits from hydraulic brakes, a large LCD screen with a phone charging port, lightweight pedals, a sports seat and wider bars for additional added stability.” Road.cc’s Electric Bike of the… Read more →
Being tall can mean needing a longer seatpost, so Yuba offer one in both Silver and Black at 500mm in a 30.9mm diameter (USI). This makes for the ideal upgrade for Mundo, Curry, Supercargo & Supermarché Series. It also helps when you share your bike between smaller/taller riders: simply cut the original seatpost to suit the height of the smaller rider (if required), add a new saddle to this one and then ‘quick release’ between units. • Alloy • 30.9* 500mm USI type • Available in Black or Silver

By sticking eyelets either side of the wheel, Yuba are able to provide a locking bolt to block the wheel for quick pitstops and back-up. Simple, huh? You can take the Frame Lock with you everywhere you go as it is extremely light: it rests on your Yuba’s frame’s mounting points while not in use too, so you will always have something to keep your Yuba immobilised. Combine this with a sturdy lock to go through the frame, around something solid and back via the other wheel. Compatibility: • Boda Boda Series V3 • Curry Series • Yuba Mundo Series… Read more →
Zapp’s i300 is the world’s fastest accelerating scooter, with the handling and stopping power to match. This uncompromising bike leaves all 300cc models behind – and plenty of other vehicles as well!

‘Wearable technologies’ are getting a lot of positive press lately and we agree, they can be great! The Hiplok Lite is a perfect example of the natural progression from low-tech to high-tech: for years people have struggled to balance their locks around their waists as they ride. Afterall, a chain slopping about on your bike is bound to either damage your frame or snag a wheel, jam the fork, or worse. So how does the Hiplok Lite differ? Simply put, it adds a velcro strap around the length of the chain. Instead of ‘jiggling about’ on the off-chance that your… Read more →

© 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 →
Source: The Independent. 15th of January 2014. For a country which prides itself on having given the world the Mercedes and the Autobahn, it represents a major ideological U-turn: Hamburg, Germany’s second largest city, is planning to ban all cars from its centre over the next 20 years and put thousands of commuters on bikes. “We envision a network that doesn’t just help residents to get from point A to B in a sustainable fashion,” Hamburg city spokeswoman Angelika Fritsch told the ZME Science urban planning network. “It will offer people opportunities to hike, swim, do water sports, enjoy picnics,… Read more →
A Range Rover obstructing an ASL.

All the drivers stopped and waved us (her), across. When it’s just me, this doesn’t happen. I watched an expensive Mercedes glide right into an Advanced Stop Zone reserved for cyclists, and come to a halt at the second line. Typical of a Mercedes driver, I thought. I’d think the same if… Read more →

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.

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 →
