BMX 20 inch 1500W rear hub motor kit

Posted by on October 17, 2022 Comments Off on BMX 20 inch 1500W rear hub motor kit

Q: I will be purchasing the your BMX 1500W rear hub motor kit. Before I go ahead could you please help with the following information.

1. What is the expected delivery time to the UK with the current covid 19 pandemic in the UK in terms courier entry to the UK?

2. What amp battery would I require?

3. Would my Saracen amplitude (steel frame) need re-enforcing to handle the power? ……In your opinion as I understand this is a difficult question to answer. 

A: 1. about 10 days now. (It’s faster than last month)
2. 40amp or 50amp battery
3. if install hub motor on frame very strong,very well..No looseness — No problem (We will make wheel works in the line. Shake is less than 0.5mm from left & right.. shake is less than 1mm from up to down)

Q: Okay well my best option is to purchase a customized battery from you, as you best know the requirements for the kit you sold me…..

1. For clarity the following battery is the product I need to order? – 
52V 12ah lithium battery –
Item ID #LBB521B
£335.75?
& You will customize as per your knowledge of my requirements?

1b. This battery is designed to attach to the Bottle holder screws I believe? As it’s being attached to the Top Bar of the BMX (under the riders knees) laying from back to front of bike,  A BMX does not have these bottle holder screws.
 
Do you sell a bracket that I can use to attach the battery without using Bottle holder screws? 

Or know if possible to add those type of screws to the frame of my BMX?

2. Also my precious kit purchase added around £150 for important fees…..
Will this battery have added import fees? —as not added until final till checkout on site. 

3. Do you sell a Torque arm that is compatible with my BMX hub because I want to further secure the wheel hub to the frame? 

4. Could you offer my any additional discount? on battery and (Torque arm + battery bracket if you can supply) as offering repeat business associated with Hub purchase. 

Thank you for excellent customer service I will be sure to leave an amazing Review on your website. 

20 inch 48v 52v front hub motor diy bike conversion kits question

Posted by on October 16, 2022 Comments Off on 20 inch 48v 52v front hub motor diy bike conversion kits question

Q: Hello! I have been viewing your various 20″ 48v/52v front hub motor diy bike conversion kits and I have a couple of questions.

1) Is there a way to install a disc brake rotor somehow next to the hub motor and still function properly? If so, can you tell me maximum rotor size allowed for these kits?

2) What type of battery would you recommend for a 48v/52v front hub motor kit like this?

Thank you very much for your time and assistance regarding this matter. 

A: 1.) Can install a disk on this 20 inch 1000w or 1500w front hub motor… but the front dropout should be 105mm or 110mm..
    Standard front dropout is about 100mm..

So if the dropout can’t be larger, can’t use disk on front motor.

2.) We recommend 52v 20ah lithium battery.
https://www.leafbike.com/products/lithium-battery/52v-20ah-1500w-electric-bike-battery-triangle-battery-1225.html

Q: Thank you very much for your quick response. Do you know what the maximum disc brake rotor size I would be allowed to install next to motor? Thank you again.

A: We installed max 160mm

Below picture. 
The dia. of two holes for disk is 44m…
If your 180mm 203mm,  aslo 44mm… You can install 180mm, 203mm disk

Q:
I forgot to ask you one last thing before making a final decision on a front hub motor kit. I know you said you are not able to ship the recommended 52v 20ah battery to Japan, but can you recommend a charger to go with this type of battery? Thank you again for all of your help and assistance. 

I just noticed the charger that comes with the 52v 20ah li battery, so I can look for battery/charger here in Japan. But, do you have in stock just the frame bag for holding this type of battery?

Ebike Breaking questions

Posted by on May 24, 2022 1 comment

Q: I have three questions so far.  One is about the Regen breaking, another is about the break levers, and the last one is about coasting.

For the Regen breaking does the controller prevent Regen breaking when the battery is fully charged so as to not burn out the controller or will I need to buy something else to prevent that from happening?

I see that the break levers have cables running from them however it says that I should buy break cut off sensors.  If those cables are not for break cut off sensors what are they for?  Also I already have hydraulic breaks so do you have hydraulic break levers that have the wiring that I need or do I just need to buy the break cut off sensors and add them to my bike?

I know that direct drive motors have drag however I would like to know at what speed, if any, it will “short” and forcibly slow me back down “some controllers do this”. And and what speed it will slow me down if any if I use it with the battery detached.

A: Regen breaking works while press braking leaver (from slower to stop,only a couple of seconds – impossible to be fully charged

Our brake lever with cut off sensors.
Your hydraulic breaks without cut off sensor.
If you don’t like our brake lever, hope use your hydraulic breakes, buy cut off sensors.. please click below site.
https://www.leafbike.com/products/electric-bike-parts/hydraulic-mechanical-brake-cut-off-sensor-switch-cable-1213.html

The direct drive motor has resistance, but it is not obvious. The power-off switch and mechanical brake must be used to stop the motor.
If the speed of 50kmh is on the flat ground, disconnect the power supply, do not use the mechanical brake, and generally slide more than 150m (if two rider on bike,may just slide 20m)

26 inch 2000w fat tire e bike kits

Posted by on May 19, 2022 Comments Off on 26 inch 2000w fat tire e bike kits

Q: I have a few questions to ask you about 2 of your kits. I have a stretcher Fat bike, That right now weight’s about 80lbs. One of the kits was 48/52 2000watt, and the other is the 60volt 2000watt 26 inch beach snow fat kit. I see that the 48/52 has a 24 mosfet controller, and the 60 volt has 18mosfits. My question is witch one would recommend for me? I did see I could upgrade to a 24 mosfet. I would I be able to exchange for that and pay the different? Last question, I have polish aluminum rims, is it possible to get that instead of  black?

A: What’s the dropouts of your fork, 170mm or 190mm?

Q：I have 170 drop outs and a single speed gear.

A: 170mm dropouts and a single speed
how fast would you like,…30mph or 40mph or 50mph

Q: My bike weighs about 80 pounds, I would like to be ably to go around mid 30’s.

A：30 mph speed ride on flat road

Q: 30 35 miles an hour is fast enough I’m looking for long rides I have a 60 volt 35 amp hour battery for it.I just had a chance to put everything together. The hub motor does not run, I recheck the 3 phase wire and they are good. I check all of the wires connector they are good. I disconnected the brake cutout, to see if that was the problem, still nothing I tried the other throttle that was sent, with the kit, got nothing. here is a picture of the display. Also how do I turn the back light on the controller.

A: We tested your 26 inch beach snow fat kit with all of other bike parts, they worked together. Everything was good.

What’s the voltage did you input?
It only work at 60v battery.  (If too high voltage or wrong connecting for + & – power wires may have issue)

Please take a photo while turning throttle check if “66’F” will be [ ], if can be changed, that means throttle is good.

Also, can hold on “down” button, if motor can work as “walk speed”

Q: OK my battery 60volt 35amh. I took the bike to a bike shop that works on e-bikes, and I paid to have it tested, the hub motor checks out good and the brake cut out is good the throttle check out good, hub motor windings are good the only thing that shows that it has a problem, is the controller.

https://www.leafbike.com/products/diy-bike-conversion-kit/20-inch-48v-52v-1000w-rear-casted-hub-motor-electric-bike-kit-1218.html

A: 1. About 10 days to arrive in Australia
2. Our self company make hub motors.

A: The frame quality of bicycle on picture is not good.

Many customers use this Aluminum bracket for 1000w, 1500w hub motor that is no problem.

If you have steel fork that’s much better.

Q: Just one lats question before I place an order.

16 inch 24V 250W front hub motor – electric bike kit

Posted by on May 17, 2022 Comments Off on 16 inch 24V 250W front hub motor – electric bike kit

Q: I have an old 16 inch bike that I would like to add electric assist on the front wheel (The rear has a complex hub/cassette that I don’t want to mess with). The hub specs seem like they would work with this kind of bike but I have some questions. Will the added weight of a front hub motor put strain on the headset? Will the hub work with the compact v-brakes that came with the bike or will I need to upgrade? Will it work with my 60 psi tires? Would I be able to power my hub dynamo lights with the battery? I am not looking for anything powerful–just something to help me up hills.
Note the attached picture is before I upgraded to long swept back handlebars which should give me enough room for any controllers and throttles.

A: This 16 inch hub motor kit 24v 250w front is fit for the spacing of 100mm fork. 
* if possible, just measure the spacing of your fork, check if 100mm? -If 100mm, no any problem. Fit for your bike, also fit for your V brake, also your fork support this motor.
This bike motor is not heavy. Works with your fork. This 16 inch rim is fit for 16 x 1.5″ or 16 x 1.75 or 16 x 1.95″ tire.
But we recommend 36v 250w or 48v 250w or 48v 500w (24v 250w is not strong)

Q:  I am just researching right now. If 250W is too weak, will the next wattage size help me up the hill? Would you recommend high or low pressure tires (I prefer low pressure)? Does the price include the battery?

A: 48V 250W or 48V 500W is okay.
If strongest, 48v 1500w low speed motor.
Not include battery.

Q: Would the 36v 250w bike motor be strong enough to boost me up hills and what battery pack would work with it? Can motor batteries be tapped to power lights originally powered from a hub dynamo?

A: 36v 250w bike motor is stronger than 24v 250w
But still no good for up hills, just work for flat road.
Also, 48v 250w bike motor is just better to work for flat road, not good for up hill.
If up hill, should 16 inch 48V 1000W, 1500W bike motor.

Q: I would still be peddling the bike with motor assist rather than relying on the motor alone. I currently don’t want too powerful a motor as my current rim brakes may not be strong enough. Also this would be the first time I rode any kind of electrified bike so I need an “entry level” set up.
One other thing, how well does the motor hold up against heat, cold and getting wet as in encountering the occasional puddle? It can get really hot, cold and wet where I live.

5 x 13T
4 x 16T 
…

Q:Which winding works well for long hill climbing without overheating?

A: 11 x 6T is not too slow,also strong.
Don’t worry motor overheating.
ONLY make sure controller is not overheating.. motor will not overheating..
** Don’t pack controller inside bag.Had better to hold it on the frame directly.It’s easy to cool controller in Summer.
** There pairs of heavy yellow,blue,green phase wires must connected well. Had better to use electrical tape winding.

Q: I saw you have a 2000w hub motor model fat bike wheel how fast will that go?
I think that may be my last question
Sorry also does hub motor have a temp sensor or can you add one please?
