Bicycle or Motorcycle? It Depends: In 37 US states and Canadian Provinces, e-bikes are considered bicycles—not motorized vehicles. In 29 states and provinces, it’s legal to ride e-bikes on bike paths; in 27 states and provinces, however, you’ll need a license to ride. Where e-bikes are classified as motorcycles, riding on bike paths is illegal. (Seem confusing? People for Bikes has some great online resources to help you familiarize yourself with the rules of the road in your state, like a link to Portland State University’s e-Bike Laws by State and Province.)
Fat e-bikes might seem excessive to some, but we sort of love the concept—especially for riding in deep sand or powder. In addition to being over-the-top and on-trend, the bike has some awesome features, and the fact that Haibike has been on the market with its sporty electronic assist mountain bike line since 2009 (and has been constantly refining it) speaks to the demand for e-bikes. The FatSix is just one of the ultra-niche e-bikes which Haibike offers. (There’s even a dual suspension mountain e-bike in the line.) The bikes are designed and built specially to be e-bikes, not just mountain bikes with motors slapped on. The FatSix features a Bosch motor and an Xduro crankset.

This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection – our Direct-Drive motors are now all High-Torque 6×9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the…
when the motor produces maximum continuous rated power of not more than 250 watts (n.b. the motor can produce more power for short periods, such as when the rider is struggling to get up a steep hill).
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.
So your motor is limited to a peak of 1490 watts. This is where you have to be careful as a number of e-bike motors are sold not at peak rating but at their sustainable rate. That 1000w rated motor might actually be capable of 2000w and be a violation.
Set the maximum speed limit of the throttle or pedal assist system. We can electronically lockout the speed to 20 mph to comply with states with Class 1 or Class 2 E-bike regulations. Just make this request in the notes section at checkout.
Compared to the torque sensor system, the cadence sensor will just provide the assist based purely on the level assist you have selected and it will not increase or decrease the assist based on your actual pedal power. You could be pedaling very lightly or very hard and it will provide the same level of assist.
Four prototype bikes, shown at the annual Interbike cycling convention that opened today in Las Vegas, will be offered to retailers. The production models will wear the traditional Yamaha tuning fork emblem, which harkens back to the company’s roots in musical instruments.

In this chapter, it tells you how to operate the bicycle or in this case e-bicycle. In most cases, there is little variation in this area from state to state. All the usual stuff about having at least one hand on the handlebars, having a light at night, riding as far to the right as can be done safely, etc. In nearly all states, it will clearly state that bikes obey traffic laws, such as speed limits, stop signs etc. Just because you are allowed 20-MPH on the ebike you can’t ride though the 15-MPH school zone at 20-MPH. You’d think this would be pretty obvious, but far too many bike riders think that no license required means no laws apply. It’s not the case. But it’s true that cops may ignore your breaking the law on a bicycle. Or…they may not. Do you feel lucky?

I’m a fan of pedal assist with a torque sensor (on high). It definitely gives the “super man” feel and allows for a great commute to work! I also like eBikes that allow for throttle override of the pedal assist while in pedal assist mode. Sometimes that extra boost up a hill is really helpful without having to switch modes to get it.
This is the bike that started it all. We launched the company on the idea that we could improve an American classic. Choose from a completely designed Fashion or Attitude Cruiser, or one of the great colors of the Classic Cruiser, Cruiser Lux or Lux Fat Tire bike.
