The mount is a set of nylon straps that are designed to be fed through the ventilation holes in your helmet, clamping securely on top. It sells for $20.

Obviously pedaling a bike could generate a lot of electricity. So the BioLogic FreeCharge exploits this phenomenon, sticking a dyno on your wheel that charges a battery-powered USB hub. You plug something (like an iPhone) into the USB and it can recharge in about three hours.

But what makes the idea work is that battery intermediary between the dyno and the hub. By charging a battery that in turn charges your device of choice, the system assures a steady stream of power to whatever is plugged in.

Obviously solar power is another obvious point of energy exploitation for those on bikes, but something about exerting myself to charge my phone really preps my psyche for the days when I'll pedal to power the robot whipping me to pedal to power him. [Bike Hugger via Gadget Lab via DVICE]

The OB1's allure is twofold; the novel, compact electric drivetrain doesn't necessarily steal the show from the rest of the finely equipped bike. The motor, which drives the rear wheel from the bottom bracket (the pedal axis) is crammed into the compact, fully-suspended frame with the batteries, leaving the rest of the bike to be outfitted with high-end carbon fiber mountain bike components.

Optibike has also strapped a GPS unit and performance monitor to the bike, which has a purported pedal-free run time of two hours. The $13,000 price may make the OB1 unsuitable for anyone who isn't some kind of independently wealthy recession-dodging eco-playboy, but Optibike is banking on about 24 of those people existing—that's exactly how many they're planning to make this year.

The systems work by detecting the shift in inductance caused by a huge metal object being in the vicinity of a charged loop of wire embedded in the road, thus knowing when someone is waiting for a light chane. Bikes, naturally, have a hard time tripping these sensors, which are calibrated to avoid false positives by smaller objects. This sensor, then, emits a signal which fools the sensors at the press of a button. Carry on, cyclists, carry on. [Plan Bravo via BBG]

Now to tackle the small issue of perspiring all over that dress shirt. [Cordarounds]

The CyFi is a wireless speaker that mounts on your handlebars. It's got a wireless protocol that runs on the 2.4 GHz frequency, requiring a dongle for your audio player of choice. There's also a Bluetooth version for your cellphone, if you swing that way. The dongle version will set you back $200, with the A2DP Bluetooth model running $180, each of which will be available on September 22nd. [Product Page via Gadget Lab]

From a technical point of view, the Trailcart is like a hybrid mountain bike and four wheeler. It's got permanent four-wheel-drive and is powered by roughly 290Nm of torque. In terms of conquering rockey terrain, it has 400mm of axle displacement. TreeHugger adds that it has a "double-action mechanical hydraulic braking system" and a Shimano Nexus 8 shifter coopted from the cycling world. The developers are trying to keep the weight at 50kg or less, in order to be transportable on automobile bike racks.

At the moment Trailcart is getting some serious investment from some heavy hitters, including Land Rover, and speaking of Land Rover, the little four-wheeler is involved in testing at Land Rover's "obstacle park" in Wülfrath, Germany. I really really want to try one of these out. There's no word on how much exertion is required to get that thing really moving, but if it takes any kind of physical strain at all, chances are it'll never make it to America.

If you are one of the few cyclists out there who is courteous enough to use hand signals on the road, the Safe Turn may be a useful device—although it looks as though the guy in the picture may have waited a little too long. Available for $18. [Product Page via Gizmag via Gearfuse]

However, I will warn you to be careful with bikes like these. Back at CES '07, I tried out a similar bike (not the 8i). And while it was 99.5% realistic, that fraction of a percent caused me to peddle much harder than necessary, and left me just short of an asthma attack. Long story short; unless you're a pro just go get a real bike, a real friend and go outside. [CNET]

The most interesting part of this product was the sexually cryptic message that came along with the link:

I saw these bike shorts and thought of you...thanks for the great 5 min each morning with my cup of coffee.

Thanks? Mitchell

The Schwinn weighs around 40-45 pounds and the battery is held behind the seat, under the cargo-area. At first glance it's hard to see that this is an electric bike, which is probably the intent. Nobody wants to be congratulated for biking only to have your congratulator say, "oh, it's an electric." – Jason Chen

Urban riders listen to music instead of the traffic sounds around them at their own peril, but if you ride somewhere safe like paths or tracks maybe you'll be interested in the iBikeMount, which lets you attach your iPod Nano to your bike's handlebars. It's a little pricey for what it is at $29.99, but you can use it on exercise bikes, baby strollers and even lawnmowers if you want to.
