Originally developed to build on Shimano’s top level component group Dura Ace, the Di2 electronic shifting system changed the roadie game with unmatched speed, accuracy and precision. Now with its third iteration, Di2 makes its debut for internal…
Electric mountain bikes have also boomed lately. Obviously the attraction of getting to the top of the hills faster and easier is there for all to see. Similarly, that assistance can balance the drag of the knobbly tyres.
Rick Hunter is a renegade cop who breaks the rules and takes justice into his own hands. Partnered with the equally stunning and rebellious Sgt. McCall, the tough-minded duo set out to crack down on L.A.’s slimiest criminals.
* Weight training. Start with good old pushups and pull-ups. You can do them anywhere, and they build strong arms and shoulders just as they did 50 years ago in my school PE classes. For the legs do squats and lunges. Again, you can do these anywhere, and you can easily add weight to increase demand. In one hunting camp, I used a propane cylinder in place of a barbell while doing squats and lunges.
One tactic that Cedric uses to achieve high speeds is by following the rules of aerodynamics, and building a bike that is as aerodynamic and as efficient as possible. The other builders on this list bypassed this step, and Cedric uses this bicycle as daily transportation on real commutes. (read our article about Cedric here) Although this high-efficiency motor uses “old school” brushes, this fact allows builders to use very affordable controllers. He has proven his design choices through thousands of miles of commuting, and the Lynch motor is highly respected.
Rambo also has several accessories for the hunter in mind. They have a universal gun and bow holder that you can attach directly to the bike frame. That way, you can focus on biking through the rugged terrain, while knowing your weapon is safely secured to the bike.
While its burly build and big tires are all about rough weather, its e-assisted drivetrain is aimed at sure-footed, reliable commuting. Electric bikes like the Pedego Trail Tracker make riders choose between motored propulsion and pedaling, but the Big Easy uses a pedal-assisted powertrain that provides an extra boost to get riders from point A to point B a little faster, with a little less effort. Motor assistance can also be useful for carrying heavy gear or helping the rider muscle through a particularly tough, sticky track of snow.
Once I received my batteries I tested each cell and each pack of 4 cells for voltage differences from the manufacturer. I then connected the four packs in series to quickly test the smart charger. Once I verified that the smart charger was working properly, I then started to install the LED balancer modules on each of the 16 cells. Each of these balance modules installed without any issues. Each 12-volt four-pack then needed to be connected in series to each other to make the 48-volt pack required to run the motor. The extra connector bars that I ordered didn’t quite reach from one battery to the other, so I flattened them down with a hammer to extend their length. The length was perfect and it also allowed me to put a small piece of cardboard between the batteries for shock protection.
To be honest its considered rather easy in the DIY community to build an awesomely fast hub motor powered bike (read our hub motor hot rod primer). All you really need is a fat wallet and the right list of components (battery, controller, and motor) which guys like Dr Bassand Zombiess, can sell you (greasypants will sell you a book to help you choose which components to buy). Hats off to the guys on this list who did it the hard way with mid drive motor systems. These mid-drive builders are – Liveforphysics, MotoMoto, Cedric Lynch, Dogati, Recumbence, and Thud.
• Extra Battery Pack – Samsung 48V10.4Ah lithium-ion battery delivers up to 19 miles of travel on one charge without pedaling and even more by adding pedaling power. Features a built-in USB port for charging electronic devices.
If there’s one category in mountain biking that polarizes opinion more than any other it’s ebikes. It’s a complex debate that charged further because of issues with land access, trail sustainability and even the legislation governing the maximum speed of the bikes.
Presented at Eurobike 2010 (where it took home a Gold Award for innovation), the Schwinn Vestige is finally hitting the mainstream market, selling in stores across the U.S. toward http://huntnbike.com end of July 2011. The biodegradable bike is made from recyclable…
Safariland Patrol Bike
Safariland partnered with Kona to create the Patrol police bike. We thought its features would ideally serve the hunter and had it custom-painted brown for better concealment. The basic bike features a Kona Racelight Aluminum 7005 frame, hydraulic disc brakes, RockShox front forks, Shimano 30-speed drivetrain, and a solid rear rack. Best of all, it sports 29-inch wheels for increased off-road capabilities over rough terrain and obstacles.
I then drilled a 3/4″ hole in the battery box to mount the keyed switch, followed by connecting the positive lead cables to the appropriate terminals on the switch assembly as indicated on the package material. With each wire connection, I made sure to use heat-shrink tubing at each cable termination. I then measured, cut, and installed the positive and negative cables needed to extend from the battery box to the XT90 connector and cable that connects to the motor. The motor came with an extra female end XT90 connector which I soldered onto the negative and positive cables from the battery box. I also use this female XT90 connector when charging the battery pack using the smart charger, since it has alligator clips and connects quite easily.
