This is the Freway Buffalo. It’s an ebike. I couldn’t say no to a free ebike to play around on, so we’re gonna have some fun with this thing for sure. It’s not a high end ebike like the Specialized Turbo Levo, but it only costs 1700 bucks whereas the Turbo Levo costs as much as a car. Although it’s marketed as a mountain bike, I’d put it in the commuter category. It’s got a big cushy seat, a really long stem, and those antler things on the handlebars. I’m not obligated to give you guys anything but the truth, so let’s put this thing together and take an objective look at it. First, let’s cruise on over to Freway’s website.
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.
You should be extra aware about your local regulations as in many countries an L1e-A certified bike needs to be registered and insured (be sure to consult your local laws and rules) and with registration comes the security that the bike can be tracked if it is stolen or misplaced. This approval that we have received is European Union wide and even those countries that are not part of the EU but rather EEA do adopt similar regulations in order to keep the market common but you will need to consult with your authorities. We will detail more about the registration process in an upcoming blog post but if you have any questions you can email us and we will respond in kind.
We're gald to announce that we finally released the new 1500W BEST system. The new motor has been possible thanks to the manual winding which offer enhanced performance. With a top speed of 60km/h on a standard 27.5" mountain bike, a torque of 150Nm, and a maximum power of 2200W ( with the 48V battery) the BEST 1500 sets new standards for high performance ebikes. It's possible to buy just the motor and controller, and combine them with a custom battery up to 72V for a maximum power of over 2800W. In addition to that, the system has the full connectivity with the Smartbox module: by your smartphone you can change the motor settings to match your daily needs. Beyond the Limits.
If you are a regular bicyclist who wants to add some excitement to your rides or wants some help with those hills, a full sized electric bike is the way to go. If you are considering a bike as a means of transportation more than an outlet for amusement, then a smaller, folding electric bike is the convenient choice. In each category, consider the speed and range you want, as these factors impact price.
If you want it to, an e-bike can replace a car, which is better for good ol' Mother Earth. Weinart says many young professionals are now seeking a "car-free" or "car-lite" lifestyle. In fact, 65 percent of people said replacing car trips was the main reason for getting an e-bike, according to a recent report. Accessories, such as racks, baskets, fenders, and even cargo e-bikes (for toting groceries or kiddos) are all available to make commuting by bike easier and more comfortable.
For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
