Jesse Jin:

 

 

Well, if she comes to the UK, I'll volunteer to show her around.

That's it then...stuff the bike, let's have more pictures of Jesse!

The triangle frame battery (probably with controller inside) has been done before, as can be seen in my Avatar of the Swizzbee.

As vfr (TUFKAD) has said there is a market for it but think in the EU it is limited, the small package is good for the motor home fraternity for occasional use. The throttle main option will cater for those wanting a lazy ride but due to its poor geometry not suitable for the taller rider who likes to pedal.

it's difficult to see where it would sit. On the portable side, you have those Xiaomi Lime scooters as seen in Paris, they are lightweight and small enough to be taken into Paris metro but if you see how the youths ride them in Paris, it's just accidents waiting to happen. The DYU beats the e-scooters with its 36V 10AH battery. On the lightweight e-bikes, it is heavier at 18kgs and does not ride as well as my new 14kg Karoo and the likes of the Orbea Gain.

due to its poor geometry not suitable for the taller rider who likes to pedal.

 

It wasn't designed with pedals and transmission, they are an afterthought. Looking at the original link from the OP reveals photos of the original, showing that it only had footpegs as shown in the two photos below so it is a moped and not a pedelec.

 

So it's hardly surprising that the design is so poor for pedalling:

 

Some of our roads are indeed terrible in the UK. My commute is horrific and a bike with small wheels would be unpleasant to ride.

 

However, there are plenty of smooth roads and there is certainly a market for a small wheeled folding bike. Our local bike shop owner actually set up a new shop in the city specifically for 'Brompton' style bikes and he is doing very well.

 

Ignore the nay sayers on here. They don't like anything that doesn't fit their narrow world view.

It's not a folding bike is it, just because the bars/stem collapse down.

Since you know nothing of us it seems such an opinion is very narrow minded.

 

Of my two most recent pedelecs, the one I've used the most by far is the small wheel folding one, using it for pleasure riding, towing, shopping, goods carrying etc, so no narrow world view here.

 

And that's the difference, it's a really practical small pedelec that's a pleasure to use in so many ways. This DYU mini-moped doesn't get close.

the Brompton has 16" wheels, hub gears, a steel frame and fork that gives a little flex to cushion the roads and also a small rubber spring. My Gallego also has 16" wheels, hubgears and neoprene spring to cushion the roads.

In practice, 16" wheels seem to be the minimum wheel size for bikes.

The DYU has 14" wheels and nothing to cushion the roads.

Hey, it's a great honor having so many replies from you in one day, I apprecicate it much. ;)And now I've to reply to you one by one.

The Gallego has Bafang geared hub motor which has clutch and is much better at climbing hills, larger16" wheels, 3-speed Shimano hub gear and it folds properly.

It's a great burden powering big wheels compared to small wheels.

As you can see, most Chinese e scooters or e bikes manufacturers choose small wheels for their pure electric vehicle, it's reasonable and it saves bike electricity when running.

Pure electricity powered scooter from

Yadea, one of the most famous e scooter manufacturer from China

Do I need to re-emphasize that my bike is mainly powered by electricity?

It looks like you're forcing a swimming champion Michael Phelps to battle with the football star Lionel Messi.

There'll be competition with small wheeled internal combustion powered scooters...

 

I agree, my knees were hurting just looking at it.

Maybe it has a place if you live in a tenth floor flat and need to only get two miles to work. Beyond that, the seating position makes it muscle ache waiting to happen.

But hang on, it's got a throttle which, in the video is the main means of getting the drive on. Isn't that illegal throughout Europe and with an uncertain position in Britain?

Can't see it having much of a market beyond being a hire bike to prat about along the sea front promenade etc.

Hey, your knees are hurting because you didn't twist the throttle. However, I have to admit that UK law is not friendly with DYU.

But it doesn't matter, there is a big market in France, Italy, Spain, Sweden, Poland, Germany, Netherlands etc. And we've successfully exported over 50,000 DYUs to USA, Singapore & Thailand ect. In a word, it's charming. And a USA sharing scooter company is talking with us on the e scooter share project like Lime & Bird.

Ridden one?

riding slowly without pedaling is very boring.

Hey, what if someone hurt his knees, doesn't wish to get sweaty, having constant short trips but doesn't want to pedal or take a taxi?

This is the reverse of the truth. The fat tyred small wheels on e-scooters are merely a continuation of them from petrol scooters, in all cases for compactness and continuing that style. And with petrol machines, the lowest powered one like the famous Honda C50, C70 and C90 machines all used larger wheels to make better use of the limited power. Image link

 

Why do you think race bicycles also use large diameter wheels with very thin tyres? It's because being more efficient they make better use of the rider energy.

I've tried several very small wheeled machines similiar to yours and disliked them all. They are all off the market now for good reasons.

So, destined for large volumes then, despite what people said on here....

Use a moped of course, you Chinese have been doing it for years and so have we. The main reason for choosing a pedelec instead of a moped is because some of us WANT to cycle using pedals, for exercise and enjoyment.

 

Of course your DYU is a mini-moped, so it could be useful for short trips of a couple of miles or so, but please stop trying to convince anyone that it is a serious pedelec that we could use for the pedelecing that most of us do. It isn't, which is why some of us have called it a toy.

Not mine, I don't want one of these, the wheels are too small for me, my commute is 12 miles and the roads are terrible. I'm also 6'4". My Gtech is an excellent bike for my needs (despite what people have said on here)...

 

That said, I can see a huge potential market for them if they come in at the right price. Look how many appollo bikes are out there.....

Relevance?

 

We are commenting for Europe, Jessejin quoted 50,000 DYUs to USA, Singapore & Thailand and none of us are arguing with that.

 

This claim, "there is a big market in France, Italy, Spain, Sweden, Poland, Germany, Netherlands etc. " and for our UK market is what we are are arguing about. One only needs very limited knowledge of the pedelec market in these countries to know that any sales for the DYU will be very limited. It won't help that it has a throttle which is illegal on a pedelec in all those countries.

 

I'd suggest Jessejin tries some of their forums to see what reactions are received there as well, there will be enough English speakers in them to understand and comment:

Again where is the relevance, Apollo Bikes are big wheeled and totally different.

Relevance is:

 

Just because you lot don't like it (see the Gtech thread), doesn't mean it won't sell.

 

Just because its cheap badly designed rubbish (see the number of Appllo BSO's in the country), doesn't mean it won't sell.

 

In my opinion (and lets face it, its just opinion on this thread), these will sell and do well if priced low enough at POS. If these were £300-400 they will sell buckets of them...

 

I can think of loads of situations where these would be excellent:

Holiday parks

Huge factory layouts

Commuting short distances in Norfolk

 

My original point was that there is a lot of talking down on this forum of anything that doesn't fit in with a few individuals views of what a Pedelec is. You lot need to be a bit more open minded. You're berating this machine based on a few pictures on the internet, you've never seen one in the metal yet you're predicting its instant demise. I'd suggest that 50,000 units shipped, its already pretty successful, and if they hit the £300 mark (unlikely I know), I'd probably buy one myself.

they can't get the street price down to that level, even if they assemble in Cambodia. There is only a tiny saving on producing something like the DYU compared to some small 20" folding e-bikes that you find in supermarkets or like this one from Halfords:

1) I haven't predicted its instant demise or even said it won't sell. What I have said is that it isn't the improved pedelec that will take over the market that Jessejin seems to think it is. It's a greatly reduced capability one that will have very limited acceptance.

 

2) As I said 50,000 shipped to USA, Singapore & Thailand etc is meaningless in terms of the EU/UK market we're discussing, so why raise it again? With over 300 millions population in the USA alone there are more than enough well to do Americans alone to buy 50,000 for their kids to play with in their wide open spaces.

 

3) And as you've acknowledged and Woosh has enumerated, it won't retail at anything like £300, it will be on the threshhold of existing more capable pedelec models from Woosh and Kudos, those starting from below £600.

 

But as I've posted, why doesn't Jessejin just send them here instead of wasting time arguing with us, if DYU are so certain these bikes are brilliant. And if Jessejin uses the links I gave to the other European pedelec forums, the views received there will probably reinforce what we've posted.
