Yuba: Supercargo (Bosch Cargo Line) & Classic Series

Yuba’s Supercargo takes a decade of experience with Cargo Bikes in a whole new direction: up front! A frontal load keeps your cargo as low as possible and right where you can see it.

The bay has a number of options as well: choose between the lightweight Open Loader, or Bamboo Box, with the Bamboo Seat Kit. Any cargo which can be strapped down securely is welcome… Read more →

There is something so very beautiful about a perfectly designed bicycle, which shines through from each and every angle.

With over a decade and a half since the first Longtail Family Cargo Bike, Yuba’s ultra-compact FastRack tucks a succession of clever design features into a surprisingly capable Shorttail.

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. 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.

Grin: 1900 Lumen Front LED Light (with switch)

1900 Lumens is far brighter than most of us need for normal rides, however nightowls may well find the full beam on the Front LED Light ensures a decent spread for off-road riding at night. The handlebar mounted switch on the extension cable allows you to toggle between low beam (600 lumens) and high beam (1900 lumens) while riding, as well as being a remote on/off switch. With 12-60V compatibility, most custom rigs can support it too. It connects to the Superharness and/or can be connected directly to your main battery supply using the 50cm long cable and 5.5 x… Read more →

Grin: Mini OLED Display and Switch

The Mini OLED Display is our recommendation for pairing with the Superharness. It integrates a power button on top of the screen, up/down buttons on the surface and can be installed on either the handlebars or elsewhere if desired. Presenting your speed in large digits alongside battery capacity, with the icon to show whether your lights are on or off (actioned via the toggle switch), is really useful information. You can also toggle to show your average speed/distance(s) covered and so on, if you feel like it. Resetting the trip after recharging your bike means you can be confident in… Read more →

Grin: Digital Regen Brake Cable (Magnetic/HiGo 4 Pin)

Proportional regen braking is supported by the combination of Phaserunner/Baserunner motor controllers and Superharness, which adapt to both your speed and bike weight on the fly, so a gentle pull on the brake lever feels a lot like conventional engine braking, rather than when a brake pad makes contact with the disk. The advantages include recharging your battery by turning your hub motor into a dynamo (typically between 5-15% in city traffic), making it ideally suited for riders who cover a lot of miles, although that is eclipsed by the reduction in wear and tear on your brake pads and… Read more →

Grin: Phaserunner V6 Series

MiRider: GB3

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 →

Yuba Accessories: Frame Lock

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.

The journey rapidly becomes the best bit when the old rigmarole of loading and parking are both sorted in seconds.

The Shed: Secondhand Bikes, Bits n’ Bobs

We call it The Shed. That mystical place where stuff nobody’s quite sure what to do with pauses for an indeterminable time, often the stuff of past dreams with great potential for the future… yet the one thing this stuff retains, is a value to somebody… once that special person begins their quest. It could be a bike we used to Demo, one which was traded-in for a younger model, a box of obscure bolts, or a charger for a bike you have in your Shed… maybe the solution to that thing you’re thinking about right now? Ask, we may… Read more →

Alta Motors: Redshift MX

Production timelapse We’re huge fans of Alta Motors and have been very keen to offer the full range here in the UK ever since they went into production in late 2016.

Notabag Reflective: High-Vis Bag4Life

Meanwhile, the inner portion comprises a storage slot similar to the tote bag you already use to take your groceries home. Enter the Reflective Bag for Life: it’s tailored for cyclists! Where it gets really clever is that the straps transform it from a carry bag to a backpack, so you can carry it in your hand inside a shop (whilst you load it up), then wear it on your back as you ride home.

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 →

Auto ban: How Hamburg is taking cars off the road

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 →

Expensive cars and driving psychology

A Range Rover obstructing an ASL. Source: The Peeky Rider. http://hedgehogcycling.co.uk/ 20th November 2013. “I was crossing the road at the same time as a pretty, young, blonde girl to the pedestrian refuge in the middle, then to the other side, crossing two lanes of traffic each time. 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.
