I have cerebral palsy and have used a powerchair since I was three.... About a year and a half ago I applied for a grant from the Challenged Athlete Foundation for a handcycle. While I was waiting for letters to go out I worked out at the gym. I was talking to my trainer about handcycles. I explained that because all of the weight was behind the drive wheel in...
Certainly very excited about this e-MTB. Bulls has decided to make use of the super powerful Shimano Steps E8000 motor. With a 500 wH battery and a 250 watt motor, this bike will assist you up incredibly steep hills but not burn too much of the battery. Bulls also sets this bike apart by setting it up with Shimano Di2 electronic shifting and a Deore XT drivetrain for precise and quick shifting. The other specs are about what you’d expect from a ride in this price range. Magura MT5 hydraulic disc brakes, RockShox suspension with 150mm of travel, and Rocket Ron tires on tubeless ready rims let you take on any mountain trails.
The Ancheer folding electric mountain bike does have a few weird quirks. The first is the handlebar mounted battery. It saves space for the folding mechanism, but looks odd. Fortunately it has very little effect on handling because it is mounted so close the head tube’s pivot point. It does raise the center of gravity of the bike a bit, but the difference is small compared to how much you raise the bike’s center of gravity.
As the weather begins to drop and the snow starts to fall, it is increasingly important to know how to properly care for your electric bike and its Lithium-ion battery. It may be possible for some people to ride their bikes during the winter months, while others must pack them away until the warmer weather returns. Whether you plan to ride in the cold and snow or if you decide to...
The Brose motor puts out 250 watts nominally, and can peak up to a max of 460 watts. That’s around half what the 2016 Specialized Turbo S road bike we tested last year develops, but that bike’s much-larger motor sits in the rear hub, which would massively compromise performance on a full-suspension mountain bike like this one. Spend up to the Expert or S-Works spec Turbo Levo and you get a motor that can peak up to 530 watts.

Between the 4″ fat tires, full suspension and the powerful 750W motor option with the Buzzraw X750, this e-bike should roll over just about any obstacle. While I’d love to give you more specifics about pricing and exact options/availability, Coast Cycles isn’t quite ready to release that info.

Mountain biking is all about having fun, right? About getting out there, enjoying the great outdoors, exercising your body and freeing your mind. So what if we told you there was a type of bike that lets you ride further, faster, and have even more fun? One that even made you LOL on the climbs? You’d still have to work for your rewards, but by assisting your efforts, it allowed you to wring every little drop of enjoyment out of your rides.
My second e-bike, and it is amazing. 40 miles range on full assist, 4 levels of torque sensor assist, one level cadence sensor assist, one level throttle only, 20 speed, forks have 120mm of range, and the 500 watt battery is very powerful. The seat was too hard, so I replaced it with a gel seat and installed a BodyFloat under the seat. Also installed a rack.
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.
Home is the one place you can feel comfortable in your own skin. You can be yourself, invite people in, or close the door to the world. To be 'at home' on the Ruby is to shut out the negative, to truly relax into who you are. If that's someone who's into the harshest of roads? Relish in them. Or if you want the smoothest ride in the world? Welcome home.
Two years worth of research and development may seem like a long time for a mountain bike but when you take a closer look at what Rogue Ridge accomplished in that time period we’re confident you’ll appreciate the work. For instance, each offering hosts a best-in-class 1000-watt motor and 13 amp hour battery to help keep this electric fat bike at the ready whenever you are. Also, with said set of fat tires, any terrain from sand to mud; rocks to snow, is within your grasp. Additional features include a full-color digital display, a range of 29 miles without pedaling, and a tech welded 6061 aluminum alloy frame among many others.
There’s a feeling people get when everything just clicks on a ride, and the Roll is a bike that pulls it all together for you. Take it on a bike path and enjoy the smooth ride afforded by a lightweight frame and Ground Control Positioning. Feel the confidence a wider, more stable tire provides. And ride longer with the Body Geometry science that’s gone into the saddles, grips, and pedals. Get out there, get active, and feel it for yourself.
Often times, carbon gets all of the attention, but as our Senior Advanced R&D Engineer, Chuck Teixeira, says, 'If you haven't ridden an aluminum bike lately, you haven't ridden an aluminum bike.' And the same reigns true for the Men's Chisel. It packs some serious XC-prowess into an aluminum frame, making it the most durable, value-packed XC bike out there.
A couple of days ago I went out with my 16yo son on our regular bikes. I soon realized that I can, at 52, no longer keep up with him and pushed myself way beyond what I should have. When we got home I seriously thought I was going to have a heart attack and had to lie down. I was very upset as it dawned on me that as my son got faster and faster I would get slower and slower and that meant I would hold him back on our rides. I decided to investigate and went online to see what was available to help me. I had never heard of Pedego but on a search a Pedego store came up that was a few miles from my home in Fort Worth, TX. I called and spoke to owner Vicky. I asked what time the store stayed open till and she said 5pm. I said j worked until 5pm and she immediately volunteered to stay open later for me to go down to the store. I arrived at 5.30pm and by 5.45pm after a test ride I had purchased my brand new Ridge Rider!! WOW! What a spectacular machine! I drove home perhaps a tad faster than I should have and my son and I went out for a ride. We did the same ride from a couple of days earlier and although I broke a sweat I got back home and felt great! Thanks to the amazing torque of the APS and buttery smooth gear changes I managed all the hills and slopes with ease and saved the flats for actual pedaling under my own steam. Thanks Pedego, you might just have saved my life!!
This Saturday, Oct. 7, Tim Sway will showcase his “UpTriCycle” at the Greater Hartford Mini Maker Faire. Sway calls the UpTricycle an “off grid, electric, solar charging mobile maker space and carrier for upcycling makers.” He uses minimal tools and footprints in his creation for unlimited potential. On his YouTube page, Sway made a comparison video between a gas-powered trike and an electric trike. He purchased a gas-powered trike first,...
Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don't require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
