Front Hub Motor (Front Wheel Electric Bike Conversion Kits)

The front hub motor is the simplest and the easiest way to convert your normal bike into an electric one. In this type of bike conversion, all you have to do is replace the front wheel with the motorized wheel, and the rest of the bike remains exactly the same as before.

Most of the time a front wheel conversion kit features a front wheel with a hub motor, a battery, speed controller, electric brake handles to cut off any power while braking, an LCD display panel, and throttle which is either a twist throttle or a thumb throttle.  Also with front hub motors you may or may not get a pedal assist sensor, so you do have to look out for this feature.

Here are some of the best front wheel electric bike conversion kits

A rear hub motor is considered a bit better than the front wheel conversion kit because it provides you with more control and traction when you push that throttle. Also, almost all the manufacturers that are building electric bikes feature a rear hub motor unless it’s a mountain bike.

Rear wheel electric conversion kit features a rear wheel with the hub motor which goes unnoticed since it looks much like an oversized traditional bike hub. It also includes a battery, speed controller, electric brakes, an LCD display panel, throttle, and almost all the rear wheel conversion kits come in with a pedal assist.

Here are some of the best rear wheel electric bike conversion kits

1. AW 26″x1.75″ Rear Wheel E-Bike Conversion Kit
2. Voilamart 26-inch Rear Wheel Electric Bicycle Conversion Kit

Mid Drive Electric Bike Conversion Kits

NAME	Bafang Kit	Bafang Kit	Bafang Kit
CONVERSION KIT TYPE	Mid-Drive Kit	Mid-Drive Kit	Mid-Drive Kit
MOTOR POWER	48V / 750W	48V / 1000W	36V / 500W
MAX SPEED	22-24 mph	28 mph	22-25 mph

In mid-drive electric bikes, the motor is integrated with bottom bracket and cranks which places the motor at the center of the bike and in turn, evenly distributes the weight of the motor. That’s the reason why mid-drive motors are considered the best option for any type of off-roading or mountain biking, where you need your bike to be perfectly balanced.

Though mid-drive units are a bit more expensive than hub motors but it has its reasons! Also, there’s a reason why most of the people prefer mid-drive units.

In a mid-drive or central system, the motor is directly connected to the crank drive. So as soon as you start pedaling the motor drives the crank arms which can now take better advantage of the range of gears. Also, a torque sensor can now easily measure the amount of input from the rider.

So what this sensor does is that it automatically varies the amount of assistance from the motor with the intensity of the rider’s pedaling that creates a smoother and a more fluid riding experience for the rider by precisely varying the amount of assistance from the motor and simply by matching the amount of intensity of the rider’s pedaling.

Apart from that many of the big brands like Yamaha, Shimano and Bosch in the e-Bike industry offer top of the line mid-drive units but the problem with those mid drive units is that they can’t be fitted in any bicycle frame, so you need a frame which is specifically built for these drive units to give you the best performance. But don’t worry there are some brands for you too!

So I’ll suggest you look for brands like Bafang or 8fun which make some of the best quality mid-drive units that can be integrated on any bicycle frame.

Here are some of the best Mid-drive units in the market

1. Bafang 8fun Mid-Drive Electric Bike Conversion Kit
2. Bafang BBS03B Mid Drive Electric Bike Conversion Kit
3. Bafang 8fun Mid Drive Crank Motor 36v 500w BBS02B DIY conversion kit motor
4. Tongsheng TSDZ2 Mid Drive Motor Conversion Kit

Mid Drive Electric Bike Conversion Kit Reviews

#1. Bafang 8fun Mid-Drive Electric Bike Conversion Kit

Check the latest price on Amazon.

The first mid-drive electric bike conversion kit is from Bafang and is quite an expensive one. But is by far one of the best mid-drive units that you can get for the price. You can get this full kit for around $1000 but don’t worry because for those on a tight budget I’ve also got some affordable options.

But remember this is the best option if you can afford it, with a 750 W motor and a 48V 12AH water bottle mount Lithium Ion battery you can hit the road as soon as you get it and it can take pretty much anything that you throw at it, either it be steep hills or mountains; this system is ideal.

Like any other powered bike, this mid-drive system gives you two working modes; you can either switch between the pedal assist or choose the throttle only mode which will give you a burst of speed (ideal for pulling away from traffic lights).

Other than that the mid-drive conversion kit features

• BAFANG LCD display which shows all the info like speed, battery percentage, mileage, pedal assist level
• By default, the bike comes in with push throttle, but you can request the manufacturer to feature a twist throttle when placing your order.
• Brake levers that safely cut off any power from the motor while stopping
• Mid motor controller which controls the different levels of pedal assist
• Speed sensor and magnet

Overall its quite a complete electric bike conversion kit as it’s got everything that you need and will perform as good as it looks on the paper.

#3. Bafang BBS02B Mid Drive Crank Motor Conversion Kit

Check the latest price on Amazon.

As we are moving down the list we are moving towards more and more affordable options; these mid-drive units offer you the same high build quality and performance, the only difference is the power.

This particular mid-drive kit comes in with 9 different pedal assist modes; one is a non-assist mode apart from that you can kick in that full power by pressing the throttle at any time and in any mode that you’re in.

Just like the other e-bike conversion kits Bafang BBS02B also comes in two different types of power options that you can choose from

1. 36V 500W Motor with approx. 16-22 mph speed
2. 48V 750W Motor with approx. 20-24 mph speed

You can get this mid-drive e-bike conversion kit for around $500, which if you’ll ask me is a hell of a bargain when it comes to mid-drive units that are way too much expensive. So if you are into mid-drive units this the best that you can find for $500.

#4. Tongsheng TSDZ2 Mid Drive Motor Conversion Kit

Check the latest price on Amazon.

Tongsheng is a Chinese company but doesn’t get me wrong it’s not like most of the Chinese products which are unreliable and cheaply built. TSDZ2 mid-drive conversion kit is surprisingly one of the best mid-drive electric bike conversion kits that you can get for under $400. Though it doesn’t provide many features like the other Bafang mid-drive units that we have reviewed earlier do, but it’s cheap and gives you an exceptionally good central motor that performs as good as a Bafang motor, but you have to compromise on some features.

Like there isn’t any throttle mode in the Tongsheng TSDZ2, which is the biggest drawback but if you only use the pedal assist. This bike has some serious stats as you can reach a max speed of 24 miles and on average you can easily maintain a speed of 14-20mph which is great.

Apart from that the Tongsheng conversion kit also feature

• Built-in Controller and both side torque sensor
• Tongsheng LCD display that displays speed, time, mileage, battery percentage and much more
• This mid-drive kit fits almost 95% of the standard bike frames with 68-73mm bottom bracket
• Tongsheng motor comes in with built-in torque and cadence sensor. This is what makes it good for only pedal assist and results in smoother acceleration.

So, at the end of the day, you get what you pay for. Also, this mid-drive electric bike conversion kit doesn’t feature any brake lever or battery.

The Bottom Line

At the end of the day, it all comes down to you which electric bike conversion kit you choose, either you prefer a hub motor or a mid-drive unit it’s your call! But before going for a particular e-bike conversion kit just ask these two questions.

1. Where and how I’ll be riding mostly?
2. What’s my budget?

Riding

First of all answer your first question. If you’ll mostly be riding on flat surfaces and paved roads where you don’t need that much power of a mid-drive unit to climb steep hills and just need a bike for casual riding around town or for the daily commute to and from work than a hub motor is perfect.

On the flip side if you live in an area where you have to do a lot of climbing on steep hills or like to take your bike off-road on mountains and all, then a mid-drive unit is perfect for you. Also if you’ve got a mountain bike, then it’s out of the question which type of conversion kit you need. Just go for the mid-drive unit.

Budget

In most of the cases, a mid-drive unit will work fine in any kind of situation, but the thing is that they are expensive. So when going for an e-bike conversion kit, have a specific budget in your mind and make sure that you stick to that budget.

Final Advice

My final advice for you is not to be put off by all the different e-bike conversion kit technologies out there and think of it as something that’s not a cookie cutter product; it’s an opportunity for you to build something with your own hands and find that perfection in it.

Also do let me know which electric bike conversion kit you choose, or if you need any kind of suggestion from me or want to give your opinion hit me up in the comments section.
