Bewo, New Crank-drive Motor

[opperpanter]

My bafang bbs02 750 watt, 25 amper motor kit unbox with c965 display...

This thread is about the Bewo motor... Your video is already in the bafang thread.

 

[tomjasz]

eMax, I want to try the Bewo system also....do you have a link where to order them? Is the system adjustable through software like the Bafang?

Go direct. They do negotiate a bit.

:lol: thanks for posting it again. Just what was needed. Sorry but I'm laughing. :lol:

Haha, LOL. Yeah posting with Tapatalk can be messy. Managed to remove it now.

They only have 250W and 350W model... any chance to have it working reliably if I fit a 48V35A controller on it?

Wh/km isn't a good way to measure efficiency

yep that's true because thats only one measure, you also have many other variable ,wh/km is only useful to compare if you also compare at the same time:

- average speed over a large distance
- total weight of bike and rider
- road flat or hilly
- wind and aero etc etc
- peddling effort.

Do you have a working site link ?
The main BEWO site doesn't seem to work for me .
Any other suppliers ?

So can you use the standard controller for the BEWO or do I have to order a different one? I am on the point of ordering a Bewo kit but I have to be sure it works ok with the standard controller.
If its just a shunt resistor, I can exchange that for a different one.

UPDATE
I have been running this kit for a while now at 36v500w. Seems solid and decent 12-15Wh/km efficiency is being achieved on most rides. In comparison a BBS01 getting 9/10. I always do 3 laps of centennial park in Sydney to test efficiency (gently undulating and surfaced). I put this down to the extra level of reduction in the BAFANG. My biggest problem with BEWO is the cranks feel a bit 'cushy' to pedal. Does not feel as direct as a non powered bike or the Bafangs.

I have run with both the regular controller and a CA3/Infineon setup. Both work well but hard to dial the Grin combo to be as smooth as the stock controller with PAS.

If someone in Aus wants one of these I'm happy to send at my cost price (I bought a spare).

Excellent! Thank you!

Great info. Could you compare the bbs01 and bewo kit a bit more?

In particular, I would like to know whether the bewo kit is more silent than the bbs01. My bbs01 has a distinct whine from the engine when it runs at 80 RPM. I would guess that bewo does not have this, in especially when using a sinewave controller?

I would definitely say the BEWO is noisier. It uses all metal gearing. There is no nylon reduction gear like the Bafang. Another thing which bugs me about the BEWO is the amount of time for PAS to kick in when you start pedalling. I have been through all display settings and seems I can't refine much further.

eMax, is the BBS01 you are comparing with a 250W, 350W or 500W?

Its the BBS01 350w motor. Performance is very similar to the BEWO at 500w in terms of torque / top speed.

Thank you for the reply, but I am a bit disappointed. The BBS01 also has a metal-metal gear, so I hoped that the sine-wave controller would make it noticeable less loud.

The quest for a silent mid-drive continues...

silent, great torque sensor, small, reliable unlike bafang.

Looks good. I like that it has an integrated controller. Who makes it? What are the specs and dimensions?

It's made in Japan as far as I remember, but don't know any details, other than it's custom made. You should really see pictures in the ad (press that little magnifying glass above the picture and browse all 12 picture ) or send a mail to them.

 

[tomjasz]

I have 3 BBS01's running and can't hear a thing. I do wear hearing aids and even with them cranked I hear nothing.

Ok. It sounds like it's a bit early to say if it's more reliable than other systems though. I hope to see more reports. I did look through all the pictures before asking, but couldn't find any specs.

I can hear a faint whine from mine. Not an unpleasant sound. I have exceptionally good hearing. I expect to hear more of it when I put one inside my velomobile.

Are you saying that your TOYOTA car has a different behavior compared to a FORD?
You should contact BEWO immediately, so you to return those KIT an be partially refunded.

Metal gears makes noise ? feel a bit 'cushy' to pedal? WHAT DID YOU EXPECT WHEN YOU SELECTED A 500W direct drive?
Definably the 250W BEWO KIT has less resistance to pedal with out power compared to 500W, but this is something to bother you only in a emergency situation.
Even with depleted battery to 95%, when the KIT it does cut-off for regular use, you may restart it and use only PASS 1 so this to absorb any mechanical resistance caused by the BEWO KIT gears system.

I have made 963 kilometers with my BEWO 250W KIT up to date, with out the slightest problem.
And I do sleep happy at nights by knowing that my fate with it will be totally different from others who selected Bafang Mid drives.

:lol: Nothing changed then.

But this may be interesting - it has a torque sensor apparently.

Yes more information. Hopefully it installs and doesn't mount like that silly Bewo mount.

 

[riba2233]

It definitely has torque sensor

Price from electrom is actually not bad, since it's EU seller, and after you add shipping and tax from china, you get about same price, but without EU customer service.
