eZee Conversion kit

Hi flecc
I think the 11-speed Alfine has a range of 409% but I may be wrong?

 

[flecc]

It could be, I don't remember, though your figure is more in line with Shimano's preferred ratio widths. Hub gears in general do have wider ratio spacing than derailleurs, utility convenience rather than best efficiency where derailleurs usually win anyway.

Personally I don't mind wide spacing on e-bikes since the motor helps bridge the gaps, especially on throttle control bikes.

Dear Big Chief Ezee Bikes

If you do have the advantage of age you should know better.

I will resist knocking your product, but please grow up. You know you are simply lashing out with badly researched nonsense to try and increase sales for the flagging Ezee range.

Best regards

David

Oh my god you do have a lot to learn about dealing with Chinese people. This man has been dealing with electric bikes to my knowledge for at least 10 years, before he started his own company he was a respected manager for another large electric bike manufacturer in Shanghai. Sure he has made some mistakes with his bikes every manufacturer does, but don't accuse him of not knowing his business and don't disrespect him on a public forum.

Clever Flecc!!

We tried the Nuvinci N360 CVP/CVT in China and believe the new version is absolutely amazing, we will be using a carbon belt drive on a new hollow forged crank to complete the set up.

A set is on the way to Australia now for Guim to test for us over 1000 km.

All the best,

David

Not at all Dan, I totally respect him or used to! I did not accuse him of not understanding the business.

Having spent months in China employing people and working with my suppliers I can assure you I understand and respect the Chinese and Taiwanese people more than you think. That is why I was so surprised to find out that the author of this anti Wisper rubbish was a respected member of the electric bike community, I thought it was an over zealous teen age sales rep.

Ezee bikes are quite good, I have never disputed that, of course I could pick fault but I consider knocking competition in open forum very poor, professionally speaking. That is why I believe that his taking cheap and inaccurate pops at our bikes childish, insulting and not very bright, I would never resolve to such cheap tactics. I defend my right to explain that point here.

I wonder if that new 360% hub you are testing is the Nuvinci N360 CVP/CVT Fallbrook Technologies Inc. ? The old hub which I think has been around for a couple of years never really got mainstream interest. I gather the new hub is lighter and also has the extra range over its predecessor, may be more appealing. The Idea of continuously variable drivetrain could be very nice on an electric bike, but would only work with front hub or crank drive through chain or belt system.
I will have to keep an eye on developments.

Hi VHFman

Yes you are spot on, the new model is 1kg lighter and has and amazingly fluid transition between as you crank up from low to high. jkirkebo will love them too it as there are an infinite number of settings so the gears could not be closer.

After just 10 minutes riding the bike you find a cadence that suits and you almost automatically change the setting to suit the road conditions and speed you want to travel. Of course all changes made to the ratio are as smooth as silk and you never have to stop applying power to the gearbox even during ratio change..... genius!

I agree, this looks very promising! It even has a twist shifter, and it supports disc brakes. I might actually buy one when they become widely available, fitting one to the Forza should be no problem.

I don't bother with building wheels though, hopefully someone will sell them laced to a nice, sturdy 26" rim.

The Batteries that are also available with the casing behind the seat post are :
37V 10Ah , 37V 14 Ah Li+ Polymer , and 37V10Ah Li+ 18650 samsung cells.
We could also have 48V for this but it is not in production yet. The whole process is not so simple as it seems. Beside being able to arrange the cells in the box, we have to design the BMS circuit that will fit, and then lots of testings including vibration tests and drop tests and etc.

The new controller could take anything from 24V to 48V nominal battery packs. You might to wait a little bit until we have the 48V battery in your battery type. The new controller would not make any speed difference vs the 37V battery and controller, another word the speed would be the same for a given battery for either controller type.

Have you considered making a bigger casing for the bike batteries ? My LiPo battery on the Forza is ~37cm tall, with my long seatpost I could fit a whopping 66cm tall battery. Most people can't, but a 50cm tall version would be usable by nearly everyone.

50cm tall battery casing should probably fit 90 pcs. 18650 cells (instead of 60 in standard casing, 3x5 and 4 tall). 6p15s LiFePO4 @ 1.5Ah in a 3x5 and 6 tall stack.

I'd love a 48V 9Ah LiFePO4 battery

Is the new 48V kit battery 15s or 16s ?

I made a slightly taller casing NiMh battery for my Torq to use some of the space for a higher voltage. Here's the modified case alongside a standard eZee battery:

I made a table comparing Wisper 905SE vs Forza, and exposing further the fact that you listed Alivio as the gears misleading customers as though the whole drive train is Alivio, while it is only the arm or derailleur is Alivio, whereas in fact the cogs or sprockets and the shifters are low end Tourneys which are not mentioned. I made the table on the same day after I saw an advertisement on the back cover of a major news magazine comparing Sun and IBM servers with glaring difference in specs and performance. People buying servers one would expect to be IT experts, yet they don't know better? Informing customers of FACTS , I don't consider to be childish nor cheap. You have not defended anything except making a big ruckus, denials, name calling and digging out history of our past problem.

Is the new 48V kit battery 15s or 16s ?

Yes, I have considered that long ago, but I thought the option to add a secondary battery in parallel along the carrier would be a better option.

We have in the flat casing 48V8Ah Ah is 13S4P, 48V10Ah is 13S5P and 37V14Ah is 10S7P

You could easily connect the 37V14Ah or 10Ah in parallel with your current battery, we have city type carrier that goes along with this battery casing, and this secondary battey could also be locked in place.

eZee 37V 28Ah ( 2 x 14Ah parallel ) with a 100 miles range (with average speed 12.5 mph with rider 100w augmentation ) is now a reality.

Yours truly,

Unfortunately I have to carry quite a lot of stuff so I have pannier bags on both sides of the carrier, thus no space for a battery there. Also my backpack rests on top of the carrier. The only other possible solution is a taller carrier with space for the battery between it and the wheel. But I don't need the range from two batteries daily so the idea was to use a new 48V battery for commuting and carry the old 37V battery in the pannier bags for swapping in on the occasional longer trip.

My current solution is a 6S1P pack of 12Ah NiMh D-cells (7.2V) in the saddle bag, connected in series to the 37V10Ah battery.

wow. now that sounds like the business to me!!!

i can't find this info on the net anywhere. so sorry for the barrage of questions but.....

what are the options with the ezee conversion kit? do you get pure pedelec mode / pedelec and throttle assist mode / pure throttle mode?

do you have to have the throttle on all the time, even in pedelec mode?

also, to what extent can you choose your level of assist?

p.s. this forum is excellent for advice.

thanks

neil

 

[flecc]

I'm not sure what the kit has Neil. eZee have used throttle only, throttle combined with pedelec and a switchable power level control on various bike models. The kit photo does show a twistgrip throttle, but it appears as if there may be a switched power level control as well.

Best to ask Onbike for that latest information, since the impending changes in the law have tended to cause changes in controls specification. I'm confident you'll find them as helpful as this forum, but they are only open Wednesday to Saturday inclusive as you'll see onsite.

Yawn...........

Come on Chief, give it a rest now. I really don't want to get into another silly little argument with you, I have always said the cassette is a Megarange. I am not particularly bothered by your inaccurate little list however to say I mislead is offensive. From our website;

Gears

Shimano Alvio derailleur with 7 speed Shimano
Mega Range 14-16-18-20-22-24-34T

The Mega Range cassette is fantastic with a very low gear for steep hills. We have never had any problems with the unit. However if a buyer wants to buy splendid gears on their electric bike then go for a Wisper Alpino or XC and experience the amazing Alfine, one of the best hub gear boxes on the market.

I agree that we do not use the most expensive parts available in the cycling world on our bikes, if we did we would be offering electric bikes at over £10,000, which would be commercial suicide. What we do is choose the best components available at a price and quality that will allow us to offer a full two year no quibble guaranty, keep £60,000 worth of spare parts here in Guilford Surrey, have the service staff to offer immediate (within max 24 hrs) assistance and make sure our bikes and components are normally available for next day delivery. I could sacrifice this service for the sake of a named brand or two but if the bike is reliable and great to ride, I strongly believe that decent service and back up is invaluable to our customers.

Thanks for the opportunity to explain our philosophy again Chief.

Sorry to be a bore guys and I will leave well alone again now but I simply can't help but say another one of the most glaring errors on the Chief's cheap, inaccurate and silly little list is to say our saddles are cheap, they are exactly the same as the ones on his bikes! We simply buy so many now they are branded Wisper!

FYI Chief we have just had another record month, we now sell Wisper in 17 countries, we must be doing something right?

Good luck my friend.

Best regards
