7 things you want to know about electric bike

[Shuangye electric bike]

There are many types electric bike on ebike market. According to using way, there are mountain assistance electric bike, road power assistance electric bike, long-distance power assistance electric bike. And classified by type of motor, it include hub motors and Mid-mounted motors. This post will tell you seven things what you want to know about electric bike.

Why do you need an electric bike?

Maybe you just need a transportation, cycling it to commute or shopping help you save time to do other things. Maybe you just want to buy one bike can ride on all kind terrains, provide more power and climbing ability, help you faster, smoother and easier to reach top of the mountain, distant valleys and anywhere you want to reach. Maybe you just want to buy an electric bike and ride with friends. Everyone have different reasons to need an electric bike, but it is no doubt that electric bike is a good helper for people. According to different living surrounding and requirements, electric bike have different types.



Is electric-powered bikes heavy?

Of course, electric bikes will heavier than normal bike because of motor and battery. But during actually riding process, because the power addition of the electric power assist, so you do not feel the electric bike too heavy. Usually each electric bike weight not over 21-25kg, but some electric bikes equipped with a big power motor, the electric bike weight will be over 25kg. It is would be a problem without electric power assist. But some electric bikes weight are light depend on their frame material, like Shuangye have one model road electric bike (A6-R) is light weight with aluminum alloy, and you can lift it easily.

Where can I riding electric bike?

It is need to query your local legal, some countries legal prohibit riding electric bike or limited speed or limited motor power on the road. So you need to know your country or state legal clearly. Like European countries, some of them limit the power of electric bike. According to the different using way, different types of electric bike can meet their different needs. Someone want to buy an electric bike to commute, someone want to buy an electric bike to riding challenge or riding outside long time.
Based on these two situation, we commend classic frame city electric bikes and portable folding electric bikes for those who need to get out or commute easily. for example, Shuangyen A1-7 and A3AL24. For outside riding, fat tire electric bikes and mountain electric bikes are the best choice. Fat tire wheel and high power motor assist you easy to ride on different terrains, and mountain ebike is the best chioce for outside riding. Maybe Shuangye A7AT26 and A6AH26 are suitable for you.



Which electric bike should I choose?

First of all, you need to consider the material of electric bike frame. Mostly electric bike would use aluminum for they are light, corrosion resistance and durability. So does Shuangye electric bike. And you need to pay attention to other parts, like brake, some electric bike would use V-brake, some would use disc brake. Usually disc brake is better and safer than V-brake, but if just meet daily cycling, V-brake is enough for you. Tire is also a main part, Shuangye electric bike use KENDA tire help reduce replacing times and provide a comfortable riding experience. A smart controller as a bridge to manage electric bike motor, battery, LCD and other electronic parts. Therefore a excellent electric bike must made of high quality material and components.



Now it is no a easy thing to research and develop an electric bike, it need to spend a lot of time and energy to do it. For example Shuangye electric bike.

Motor

Motor - electric bike core part - is an important consideration reason when people want to an ebike. As we all know, a high power motor means that ebike will provide you more power and fast speed. And there are three types about electric bike motor, mid-drive motor, rear hub motor and front hub motor. More of electric bikes often use rear hub motor, as same as shuangye electric bikes, but a few of electric bikes will installed mid-drive motor which is make you replace ebike wheels more convenient. Front hub motor is no popular on electric bike marketing. So it is few front hub motor electric bike.

Transmission system

Most of electric-assisted electric bikes are not much different from the “traditional” electric bikes on the transmission system. However, with the development of motorcycles, accessories dedicated to electric power products will become more and more common. Shuangye electric bikes use SHIMANO transmission system which designed to provide an optimized E-MTB gear ratio range, as well as increased battery life and reduced part wear. And it is also possible to convert the SHIMSNO transmission system with mechanical shifting. Changing different gears depend on your riding situation.

Battery

How long dose electric bike charge a single charge? Usually battery decide how long motor operating time. So a large capacity battery means operating ling time. And Shuangye electric bike provide 36V/48V 9AH/10AH adapt to your need of long-distance. It can be fully charged with a dedicated charger for 4-6 hours and can be riding 40-60km. According to different requirements, and you can choose different types electric bike batteries, like hidden batteries, bottle batteries, triangle batteries, frog batteries and other. And combine with PAS system mode to help you save more electric.

As a former ESL instructor, I understand that foreign language speakers tend to use the grammatical framework of their own language, much as native English speakers do when attempting to speak another language. For sales and support of English-speaking customers, though, it would be beneficial to the company to employ a fluent English speaker to edit their print materials. It's off-putting to potential customers to try to make sense of this text.

Besides the poorly written text, I think this is a sneaky way to inject advertising/promotional material to the forum. If that manufacturer had a dedicated forum section here, then the text should go there (if even allowed) but I feel it shouldn't be in the intro section.

 

[PatriciaK]

Agreed about the advertising in this particular forum!

Just get a Rad Power Ebike!!

Within the translation world, text should always be translated by someone translating into their mother tongue.

This makes reading it much easier, but this can be expensive for some companies.

Some try to circumvent this to save costs, but you only need to read some of the write-ups on various on line selling sites, where this has been done that make for some very interesting reads.

In your case, what is a ESL instructor ? As to the rest of your text, I totally agree.

I had to learn to read Chinesium to understand how to setup my display and controller.


When C4 = 4 is confirmed, the "percentage value of the first gear speed accounts for its full speed" of the power assist gear flashes, press (UP) button or (DOWN) button for short to make selection, and the default value is 50%.

I'm still not sure, but I think I know how to set C = 4 now.

Kunteng needs to hire a ESL translator.

Perhaps @PatriciaK is available to translate their owners manual?

Wife once bought a very fancy Japanese chef's knife. The poorly translated instructions advised to "keep out of children". Good to know!

 

[Slaphappygamer]

This would actually be a great use for AI. Companies can use that before printing instructions to English.

I would set C4 - 0 and never thought much about it. Does C4 =4 makes throttle proportional to PAS level, like 100% in PAS 5 and less in lower levels? Never knew that.

Just curious, why would anyone want that?

I use my throttle for sudden bursts of speed or torque on top of pedaling. And for that, I want immediate access to extra power, up to full power, regardless of current assist level.

The adjustable C4=4 setting is only available on the LCD8, and I think it's the only difference between the LCD3?

I can adjust the power for first throttle gear from 20% to 60% of the full power that your controller has, or what you have it set at.

I had my controller turned down to half (12.5 amps on a 25 amp KT controller) and my first throttle gear turned down to 20%.
First throttle gear would give me about 2.5 amps and a maximum speed of about 6 kph at full throttle.
It worked great when you needed to go Really slow like a grass covered trail where you can't see the trail.
I used it to do a really tight 180° turn from the side of the road.
I could just hit full throttle and the bike would go just fast enough to turn around with about a 6 foot radius.
I could still vary the throttle to go even slower, or turn it up to throttle gear 5 for full power and speed.

I didn't hook my cadence sensor, so I'm not sure if it applies to PAS modes, and I'm not sure if you have to use "Throttle Gears" instead of "PAS Modes" to use the "Imitation Torque Control" offered by KT controllers/displays?

Just curious, why would anyone want that?

My ebike came with a 750 watt, 1000 watt peak motor that was turned down to 32 kph to be legal in Canada.

The stupid thing had cadence sensing with crappy programming and would go to Full power (which was still 1000 watts) when you just touched the throttle, and first PAS mode was something like 25 kph. The bike would launch itself to that speed in about 2 seconds and give you whiplash.

On top of that, it came with a "quick" throttle which is basically an on/off switch.

I've got no problem with lots of power and speed (other than risking $5000 in fines if I go over 32 kph), but I Wanted Control Of The Power.

It wasn't just the throttle, it was the PAS modes too.
There was a guy and his wife that each had the same ebike as me and his wife crashed 3 times.
She stopped pedaling going into a corner on a gravel road (and of course the power waits a couple of seconds to shut off) then when she started pedaling again, (and waited another 2 seconds for power) the power kicked in full blast and spun out the rear wheel.
The ebike is HUGE and can carry a 320 pound rider that would need all that power, but she only weighed 90 pounds and you Can't Turn Down the power.


I could have just gotten used to it and tapped the "TURBO" button to get it going, but I thought it was just plain stupid and I ditched it to install a KT controller.

I use my throttle for sudden bursts of speed or torque on top of pedaling. And for that, I want immediate access to extra power, up to full power, regardless of current assist level.

That makes sense, but you still want a throttle that is ergonomic enough to operate easily and naturally.

This is my "Quick" throttle at zero throttle,..

And at full throttle,..

With the the dead spots below zero and above maximum, the "active, variable" movement is about about 3 mm.
There is no way to hold it steady unless your ebike is turned off.


This is the half-twist throttle that came with my new Voltbike, it's Awesome!!

I can easily adjust the variable part of it's range and if I want full power, I just crank it all the way.
