Most commercially available electric bicycles have a rated power of 250w. However, whether the 250w motor is enough to meet the needs of your electric bike is still controversial? This is a problem that most buyers will encounter, especially those who live in hilly areas.
The main difference between a 250w and a 750/1000w motor is torque and speed. A 250w motor can easily allow you to reach speeds of 20 to 25 km/h on flat terrain. On the other hand, a 750 or 1000w motor can provide a speed of 25+ km/h on any terrain type.
This makes it easier to ride an electric bike on hilly terrain. In addition, even with large loads, you need speed; a 750 or 1000w motor is more suitable. Otherwise, the 250w motor is very convenient for electric bicycles.
36V 13Ah battery has 30-40 miles of range
36V 16Ah battery has 38-45 miles of range
36V 18Ah battery has 42-50 miles of range
48V 13Ah battery has 40-50 miles of range
48V 16Ah battery has 50-60 miles of range
48V 19.2Ah battery has 60-70 miles of range
48V 21Ah battery has 65-75 miles of range
All figures are in pure electric mode, the actual mileage will be farther if there is pedal assist.
I'd like to give you the facts and allow you to make your own decisions. I'll ask five questions and give you a recommendation based on each scenario.
What Is Your Budget?
I often see hub motors on entry-level bikes, but that's not always true. A hub motor e-bike may be premium, but it's generally more affordable than a mid-drive motor. A hub drive bike will be your best option if you want to spend as little money as possible.
How Often Do You Ride Your Ebike?
The maintenance costs of mid-drive bikes tend to be higher than hub motors because more moving parts need to get looked after. If you’re worried about high maintenance costs, hub electric bikes are your best option. But, if you’re after convenience, then mid-drive motors are the better choice.
What Distance Do You Typically Ride?
The range you get with mid-drive electric bikes is far greater than that of a hub motor. So if you ride anything more than 15 to 20 miles per day, you should consider getting a bike with a mid-drive. Even though you must constantly pedal, you won't feel as fatigued riding a mid-drive motor e-bike the same distance as a hub motorbike, especially over long distances.
What Type Of Roads Do You Ride On?
Hub motors will be wonderful if you ride on terrain mostly made up of straights or even downhills. And you'll be able to take quite a few breaks while cruising down the straights.
If you have a few hills on your route, you want to consider buying a mid-drive motor e-bike because it'll assist you better with pedaling uphill.
Do You Like Taking Breaks?
The mid-motor works with the gears instead of directly powering your wheels, the motor only works when you pedal, but thanks to the efficiency of the mid-drive motor, you will feel less tired while riding. But since a hub motor applies power directly to the wheels, you can stop pedaling and still have power delivered to the wheels to keep moving.
STEP 1：REPLACE YOUR EXISTING WHEEL
Unbolt and remove your old wheel
Put on the new motored wheel
Tighten the bolts. Check that the wheel is well secured and spinning freely.
STEP 2：INSTALL ACCESSORIES
You can choose to use the bike without the throttle (required in some EU countries), but if you wish to use the throttle, please remove the grip from the handle and Install the Throttleon the left or right side of the handlebar.
Install the Power Controller and Display.
Install the Headlight and the Rear lights.
Install the Break sensor. Would you please check that the condition of the brake cable is in good condition and that the threads are straight? The sensor can be installed near the break or the handle. Please note that the sensor arrow needs to point in the direction where the handle is.
Install PAS. Remove the left pedal crank with the Toolincluded in the Kit and add the PAS. Reinstall the crank.
Note: The Kit includes many kinds of supports and screws to install the parts.
STEP 3：INSTALL BATTERY
Tube Battery Installation: For the Tube battery, screw it to the existing holes on the downtube. Check that there's enough space for the battery and the cables below.
Rack Battery Installation: For the Rack battery, please remove the existing one and replace it with the one included in the Kit.
After the Tube or Rackmount is installed,just slide the battery in place and lock it.
STEP 4：INSTALL THE CONTROLLER AND CONNECT THE CABLES.
Left Picture: In the 250W models, the controller is built into the battery.
Middle Picture: In the 1500W models, there's an external controller bag included in the Kit. You can place it on the frame itself like the top tube.
Please connect the cables and use the included ties and wrapping to fix them in place.
STEP 5：TEST THEN CLEAN UP
It is now time to know whether your labor has paid off and that you currently own an e-bike. To test these connections, you will have to run the system. Do this by doing a power cycle. Turn the throttle once it is on to see whether you can depend on the wheel's electric power. While on electric power, test the brakes to see if they can cut off power. You can test the Pedal Assist System by pedaling to see if the motor will start running. After confirming that everything is running as expected, ensure that the cables are well-secured to avoid hazards or accidents. If there are no problems, you can start enjoying the ride!
The main advantage is that it allows you to ride longer distances on one charge, which is excellent for people who live in cities or work outside the home.
The conversion kits cost much lower than a new electric bike.
It provides a purpose to an old regular bike left to rust in the garage.
Regular bikes are available in different types, including mountain, BMX, road, and folding bikes. In contrast, e-bikes have very limited variants. So, an electric bike conversion kit instantly helps you motorize your favorite bike type.
If you are a mechanical hobbyist, these conversion kits are fun to install and swap between bikes.
E-bike conversion kits are a greener option than an electric bike, as these kits help recycle the regular old bikes by converting them into e-bikes instead of manufacturing whole new ones.
It can help you to save money on gas and maintenance costs, as you will use your electric bike instead of a motorbike or car for daily commuting.
E-bike conversion kits are lightweight, so they won't add too much extra weight to your regular bike. Still, they will be much lighter than an electric bike.
