eZee conversion kit

[Leonardo]

I see on the new website that eZee is going to import in Europe its conversion kit. There are a few strange things re the weight – a 3.2 kg controller (?) and a 3.3 kg battery while the same one on the Torq is said to be 5.6 (?) - but the kit seems very interesting. Do you know which motor is this one, the same one of the Sprint?

The the original Ezee Nimh battery weighed 5.5kg, the Phylon Lithium about 4.5kg but the quoted 3.3kg refers to the new Sanyo lithium now supplied by Ezee using the same cells (but more of them) as the Panasonic unit.

The motor is the new motor designed and manufactured by Ezee themselves, first seen in the Torq Trekking and now used in the Forza as well. It certainly is nothing like that previously used in the Sprint or the 8fun motor used in the original Torq although I expect in time it will be used in the entire range.

As for the 3.2kg controller it must be a miss-print, perhaps the decimal point in the wrong place. It is the usual Ezee controller which may weigh 0.32kg at a push but I doubt it's even that heavy.

I hope that clarifies things Leonardo.

Is is really made by eZee or is it made for them by Suzhou Bafang?

Has anyone done a comparison between the eZee and 8fun motors?

It doesn't look like a Suzhou Bafang product judging by the internal cogs, which look more like those used on the larger diameter eZee Sprint motor. It could be manufactured for eZee by whoever makes that Sprint motor.

Wai Won Ching, the owner of Ezee, gives some some information on the Ezee motor in these posts, stating that it is manufactured in house.

I got the North American version of it. I have done +1700km with it, very good system. No problem to get 40km out it on one battery load. I do peddle a lot.
Price is good I paid 1100 euro (including import and TNT).
Kind regards,
Jo

I remember reading that, Ian, and at the time I thought it was very odd given that, nowadays, electric motors are usually produced in very large volumes by people who have perfected the performance and reliability. Usually they are one of the things that manufacturers outsource.

I agree Frank that it is unlikely the motor is produced strictly "in house". I would guess Wai Won used the term to emphasise that it's an Ezee exclusive product, I would imagine the actual production is contracted out to a specialist company.

But then again the motor could be assembled at the Ezee plant from parts made elsewhere?
