Things to Consider When Choosing a E-Bike Conversion Kit
If you are on the lookout for the best electric bike conversion kit, the first thing to do is to arm yourself with as much information as possible. You must know what to look for, what to avoid, and at times, what to compromise on several almost-similar models.
Ease of use
The best kit should be easy to install, use, and dismantle. Don’t buy something that will need you to use a manual and even ask help from professionals just to put it up.
Speed is of the essence; after all, that is one reason you went for an electric conversion kit in the first place. Therefore, the kit you pick must make your bike a little faster to replace other tedious or costly modes of transportation. Speaking of speed, ensure the ebike conversion kit comes with a throttle so you can modify your speed.
You can enjoy a good spin around the neighborhood if your bike runs quietly. If the motor that came with your kit is loud, it wouldn’t be prudent to use in residential areas.
Types of Electric Bike Conversion Kits
Driving experience changes depending on the type of conversion kit used. However, it’s all a matter of what works for you. Here are some of the common ebike conversion kits on the market today.
This is the most common kit on the market and is preferred by many people perhaps due to its mid position that helps to keep weight on the low. It’s also easier to change a flat tire on this model than on the hub motor ebike.
Both the motor and the battery are attached to the frame with the motor tagging on the bottom bracket. The design is okay for those who use public roads. However, if you hit the off-roads often, the exposed nature of the motor means it can easily get damaged. Another drawback is that mid-drive kits tend to cost a lot.
Front-mounted kits come readily installed on the front wheel and all that remains is to remove the old tire and drop in the new one. Make sure to use the same size tire. Only opt for a front hub kit if the terrain you roll on is level or undulating.
The rear hub kit is almost similar to the front hub kit when it comes to component composition. The only difference is that it’s been designed for the rear section of the bike.
Since most of the electrical hard work has been done, all that remains is to remove the old tire and pop in the new one. Rear-mounted drive kits are also as common as mid-drive varieties but are less complicated.
This is a special kind of conversion kit where a roller sits on the back wheel and when the motor powers up, it rolls, giving the wheel a little more push so the bike can go faster.
Frankly, this solution for speed could be a little crude as the tire gets worn at a faster pace. Besides being uncommon, the system somehow is not as efficient as other types of kits.
The motor available on your newly converted ride will determine how fast and how far you can go. For instance, a 48V motor is more efficient than a 24V motor.
There are two types of hub motors: geared and gearless (direct drive). It is the gears that provide leverage and enable smaller motors to achieve more. However, geared motors also produce more noise due to friction.
Brushless or Brushed
When choosing a motor for your electric bike, you can get either a brushless or brushed motor. Brushed motors are simple. They don't have a DC supply or battery; instead, they have an armature (or rotor), a commutator, brushes, an axle, and a field magnet.
Brushless motors, on the other hand, has its permanent magnets around the perimeter of the rotor. It requires no power and instead employs control circuitry.
In general, brushed motors are more inexpensive and reliable. They also have a simple two-wire control and can deal with rough terrain reliably. However, the brushes do require regular maintenance.
Brushless motors are quieter and more efficient. It can also last longer but it would cost more than the brushed motor.
The traditional electric bike chain drive motor provides a lot of power for uphill climbing. It is also the preferred motor for riders who want the pedal bike feel of the ebike. It basically improves the efficiency of the ebike and extends its range both on and off-road.
Friction drives on ebikes are much less popular than hub motors. They power the bike through a friction connection on the rear wheel of the bike. While it used to be popular, its efficiency problem is just too much for some riders. It wears out tires much faster and a lot of energy is lost through heat and scraped-off rubber from the tires.
Friction drive electric bicycles also cannot be used when it's rainy or snowing as a little bit of water will reduce the friction between the roller and the tire.
Ordinary braking provides friction that impedes motion resulting in a stoppage. Regenerative braking, on the other hand, provides stopping energy which also happens to extend the battery life. These types of brakes are expensive, though.
The most efficient motors convert 80% of power coming from the battery into mechanical energy that goes to the wheels. But how do you tell if the motor is efficient? You check the maximum speed. Motors that run at a speed of 25mph and above tend to be more efficient than those that run at 24mph and below.
E-Bike Batteries and Power
Battery versatility is something you need to pay attention to and a great kit should allow you to try other alternatives in case the one you wanted is out of stock. Always pick lithium-ion batteries over the cheap, old-fashioned lead-acid varieties.
Power depends on three things; watts, voltage, and amp hours. Most motors come in 250W, 500W, 750W, and 1000W. The higher the wattage, the more power a kit generates. With more power, the battery has to be larger for ample storage room.
Ampere per hour (ampere-hour) or simply Ah refers to the duration the battery lasts while on use. The larger this number is, the longer the cycling time. Charging also takes a considerably shorter time. The same concept applies to the voltage; for instance, a unit with 48 volts provides more power and range than that of 36v.
There are other minor but essential components to look out for in the best electric conversion kit. A few of them includes the following.
How would you feel when your bike’s juice suddenly runs out on you when you expected it to cruise for a few more miles? Well, with a controller (wrist wear), you can monitor your riding metrics such as speed, power output, and even the battery level status. This should help you plan your cycling and get to your destination before the motor powers down.
Pedelec or Throttle
Pedelec, also known as pedal assist, is a driving mode where the pedals rotate depending on the power delivered. Although pedaling is mandatory, less effort is applied.
In the throttle-control model, the motor doesn’t operate the pedal and hence the bike merely freewheels on the motor’s electric power. Pedaling is not necessary but you can do it if you want to save on power especially when climbing hills.
When you buy a conversion kit, you’ll realize that very few come with replacement brakes. However, it’s important to replace the brakes with an alternative that provides more stopping power, something like disc brakes.
The version of these brakes sport brake levers that look similar to conventional bike brakes although the levers are designed to stop the motor and not the wheels. They do so by safely disconnecting power flow.
Electric is the future and with countless conversion kits available, anyone can now turn their ordinary bikes into electric bikes for a little assist. Buying a kit and upgrading your bike saves you a lot of bucks that you would have otherwise thrown into a high-end electric bike.
Make a point to read as many ebike conversion kit reviews as possible before making a choice. Remember, the best electric bike conversion kit must be compatible with most bikes and simple to install. Make a choice from any of the kits mentioned here and you will end up with an electric bike you will end up using for years.
