Makita 18V Powered e-Bike Conversion Kit

[marty]

How fast will I go with no pedaling?
How far will I go on one battery with moderate pedaling?

Come on Marty. Read!
Max Speed 25km/h = 16 Miles per hour
Distance 20=+km on flat road (6.0Ah Battery) = 12 miles

16 Miles per hour is a bit slow. Great advantage of slow speed with motor vehicles. Slower is safer.

12 mile range is fine. Gets me where I want to go,

So? Stop, replace battery. Go some more. Same as you do when your cordless power tool stops working.

So in long run you can end up spending ten times more on Makita batteries than you would on average hailong battery and end up with a mountain of toxic rubbish. AtakSnajpera is quite right. To get decent power out of 18V battery you would have to double amps comparing to 36V battery.

This kit might be good for little children though. Unfortunately here in UK children (under 14) can't ride e-bikes.

Good point. In the US, for the younth.
In UK, for the children.
But in Japan and Taiwan, aged people and housewife probably need that.
How powerful or fast it is ?
Well , some gets bmmer 318 . But some goes for M3. Isn’t it ?

But if ya already have a bunch of power tool batteries. The additional cost of same batteries used for a electric bicycle would be $0.

Strange logic. If you kill batteries you have, you will still have to buy new batteries otherwise you will have bunch of useless tools and useless bike.

If my life continues as it is. I will have about 9, 18V Makita batteries at all times.
4 stay in the house for the vacuum
2 for the two big flashlights
1 in the radio
2 for whatever tools I am using at the time

Every few years a battery dies and I replace it. So yes if batteries die from number of cycles, a few bike rides will cause them to die sooner. Age also kills batteries. Same with people.

 

[marty]

Suggestion - Change your kit to use 2, 18V Makita batteries for 36V. More volts = more speed.

Mount 2 batteries to water bottle bolts or on rear rack.

 

[marty]

Thoughts on 40V. If I ever change my life to higher voltage power tools, will look at Makita, Dewalt, Milwaukee or other brands.

All the professional mechanics I know are using Milwaukee impact wrenches.

My dream is a cordless impact wrench for wheel lug nuts. I am still using air hoses.

it will leave a mountain of toxic waste behind.

Come on I am trying to replace a 10,000 pound truck with a 50 pound bicycle.

Me and planet are eternally grateful. Please keep up good work. There is a room for improvement. I have radio powered with three AA rechargeable batteries.

There is room for lower power e-bikes, the 250w conversion fitted last year to my cycle provides far more power than i ever did happily plodding along at what must have been 8-10 mph.. I do enjoy the faster speed on occasion especially uphill, but after the 'honeymoon' find myself frequently not employing the full assistance available from the motor. And trust me im on no fitness kick, exercise is and always will be a side effect never a task/goal. Im just rarely in a rush..

Sorry that I am not knowledgeable on go by magic bicycle technology. Watch this video:

If rider squeezes brake to stop. Will motor stop powering wheel?

According to the video if the motor senses deceleration it will not provide any power. It will also not provide power if it senses acceleration but is going downhill.

Cool idea. As someone else who has a lot of Makita batteries and several of their 36v (18x2) tools. Even selling a quality 36v adapter vs the garbage made for the cheap hot wheels toy conversions would be cool. I keep looking for discarded Ego mowers, No luck yet, but my neighbor does keep leaving his garage door up…..

750W and max torque only 30Nm?

Both motors are illegal in UK and EU.

A hub motor is designed for bicycles, not for purely powered motorcycles or cars. If the power is insufficient, human legs, oh, and Shimano can help. This is what sets bicycles apart from cars and motorcycles, correct?

No, not correct. Some hub motors are clearly designed for motorbikes, but it is not my point. Something is very strange in the data sheet. 2kW input power and only 30Nm? My motor is rated 250W and can deliver max 120Nm. 48V 750W delivers same torque as 36V 350W?

To sell your motors in Europe, you must rate them as 250W or lower. Otherwise they are illegal.

Just because a motor is rated for 350w at 36v and 750w at 48v doesn't mean it has it be used at those levels. For example, here are the specs on the all-in-one eHub which I was told in another thread use the same hubmotor as the Makita battery kit version:

They are different product line. One is eHUB all-in-one 250w. The other is eKITS which could be veried.

No、2 different electric design。 The bldc in eHUB is dedicated. Can not be sold separately. eKits bldc could be universal, and be sold separately.

Thanks. I understand the difference now.

 

[eKitsTW]

Thanks. I understand the difference now.

F.Y.I. The bldc motor of eKits which could be sold separately.
Price can be found in our online store 800W Geared BLDC Hub Motor
The output data has been organized and updated. The electric control current has a maximum limit of 45A, but for safety, it is restricted to 30A.

During the six years I’ve spent developing an all-in-one smart electric assist wheel( e-rim.com ), focusing on the three essential elements for electric-assist bicycles: the motor, controller, and battery, I have not only obtained several invention, utility model, and design patents but have also continued to pursue breakthroughs in new technologies and application methods.

Of course, it’s not about endlessly chasing innovation. While technological innovation is mainstream in the IT industry, what’s more needed in the traditional bicycle industry are products that are durable, simple, and reasonably priced.

After a period of experimentation, we have launched the eKits electric-assist kit( e-rim.com/ekitsen )

1. BLDC Motor: Designed and manufactured by a Taiwanese factory with over 40 years of history, offering durability and reliability far exceeding those made in mainland China. The front-wheel motor works in tandem with human pedaling on the rear wheel, aligning with the Dual Drive concept of Bridgestone electric-assist bicycles.

2. Controller: Our innovative algorithm supports 18V or 40V batteries, combining motor Hall sensor signals with an external pedal sensor to achieve a pedelec effect similar to Yamaha's PAS system.

3. Battery: Throughout years of development, battery weight, size, durability, and cost have always been our challenges, not to mention the strict regulations on battery transportation today. Fortunately, Makita rechargeable lithium batteries, used for tools, are available in over 40 countries worldwide. With our improved motor and controller system, we've made it possible to use Makita batteries.

Although lowering the voltage reduces the motor's torque, this performance is still sufficient to meet people's daily commuting, school travel, and other urban transportation needs.

Considering the price of Makita 18V battery, you will surely welcome this option.
