What is an Ebike
E-bikes are bikes that have an electric motor that is generally powered up to 750 watts. Many e-bikes are powered by pedals that propel the bicycle with or without the help of the electric motor. E-bikes travel various speeds, but most e-bikes fall into classes that generally do not allow users to exceed a top speed of somewhere around 20-28 miles per hour.
Ebike + Emoped Classes
The three classes are defined as follows: Frequently asked questions:
Class 1: eBikes that are pedal-assist only, with no throttle, and have a maximum assisted speed of 20 mph.
Class 2: eBikes that also have a maximum speed of 20 mph, but are throttle-assisted.
Class 3: eBikes that are pedal-assist only, with no throttle, and a maximum assisted speed of 28 mph.
All classes limit the motor’s power to 1 horsepower (750W).
Where do we ship too?
Currently we are shipping on within the Continental United States
How long will my order take?
Depending on when you placed your order, it will typically take between 6-8 weeks for build and 7-10 days for delivery.
What does unlocked mean?
Bikes are shipped as class 2 and follow the speed requires for that classification.
Unlocked, the bikes can achieve roughly the following speeds on average:
750w = 25mph
1000w = 35mph
2000w = 45mph
3000w = 55mph
What range can I expect?
To infinity and beyond!
Volts (V) = HorsePower!
Volts = Horsepower!
That is a pretty simplistic way of putting it but it is the closest analogy to a car. Electric bike batteries typically come in 24V, 36V, 48V, and 72V batteries. More volts = more POWER
Here is another analogy: electricity is water. If it is water flowing through the wires (tubes), then higher voltage means that the water (energy) moves faster, and through a smaller tube.
The typical battery is 36V on most e-bikes with some at 24V and some at 48V. The electric bike manufacturers spec these because they provide a good power to cost ratio.
When you get up into the 72V range you are looking at a custom built electric bike because a 72V battery will generally make a bike that is powerful and may not be classified as a traditional bicycle. 72V batteries are significantly more expensive too.
Here is another thing to consider when building or using a high power electric bike; being SHOCKED! Human skin can insulate you from shock up to something in the area of 40 – 45 volts. 72 volts is a shock hazard, and in some places that is a regulatory issue. It is always a safety concern.
If the power output (watts) or the max speed of an electric bike goes above the allowable (250 Watts, 25 km/h in Europe / 750 Watts, 20 mph in US) then the e-bike will be classified as a moped which generally requires registration, insurance, license plate, etc
Amp Hours (ah) = The Gas Tank!
Yup, it’s generally that simple. The more amp hours you have, the more range you will get with your electric bike.
Now one thing to be aware of is that every manufacturer will claim that their bike has incredible range You may see an e-bike with 36V 10ah battery that gets 25 miles and then another with the exact same battery that gets 50 miles of range. “Your mileage may vary” is the car terminology for average miles per gallon, but I think that crosses over to e-bikes range claims!
There are a lot of factors that affect the range of the electric bike, such as:
Are you climbing a lot of hills? Range goes down.
Are you riding into a lot of headwinds? Range goes down.
Are you carrying heavy cargo on your bike? Range does down.
Some bikes may have a very inefficient motor (lost energy in the motor due to friction, etc.) that causes decreased range, but these days most electric bike motors are fairly efficient (there is room for improvement!)
What is the condition of your bike? A well adjusted bike goes farther i.e. well lubricated chain, proper tire pressure, etc.
What is your tire pressure? Lower pressures = less range. There is a nice balance between too high a pressure (not comfortable) and too low a pressure (not efficient).
Are you pedaling at the right times? Pedaling at critical moments (when accelerating or climbing), you will go farther.
If you are concerned with range I recommend going with a large capacity battery pack. Some electric bike manufacturers have use a standard 30 ah pack with an option to upgrade to say a 50 ah pack.
Amp Hours: Should always be listed numerically, typically 10 to 50 Amp Hours ( abbreviated " Ah " ) a measure of how many fixed number of Amps a battery can sustain for 1 hour.. ( C rate ). Or, double the amps for half the time.. Or half the amps for two hours.. etc.
Watt Hours: This is a far more accurate way to know how much usable energy is in a given battery pack ( abbreviated Wh ) when available, this is the number to look for! Also, you can translate it into how many watts, continuous, for 1 hour! A 500wh battery can deliver 500 watts for 1 hour or 1000w for 30 minutes.... or 250w for 2 hours .. etc.. Most ebikes do not use power at an exact level, continuously, so this does not directly translate into ride time, but you can quickly see how a larger battery with more energy (capacity) can deliver lower power levels for longer periods of time, and go further on a charge.
Battery energy (Watt Hours)
500 wh x 250w 2 hours
500 wh x 500w1 hour
500 wh x 1000w 30 minutes
A word of caution, some vendors are prone to bending the truth and "over-promise" when it comes to range expectations. Be sure to do some research before you buy, ask the right questions and by from a vendor that provides range estimates in relation to your weight, bike, intended use and intended input.
Ah vs Wh: This can get confusing, but it is very important to understand the difference. Amp Hours (Ah) means nothing unless you factor in the voltage. Watt Hours (Wh) is far more important because it factors in the Voltage and the Amp Hours together and determines how far you might go on a full charge. Not all packs are labeled and/or constructed the same, so be careful and pay close attention.
Wh Example: 36v 10ah = 360wh and 48v 10ah = 480wh
Stinger Upgrade Example: 72v 50ah = 3600wh
With a typical 200 Lb or less rider, expect burn rates of 15-17 wh/mile on average. It can be much more or much less depending on countless factors but this is a realistic number to start with.
