Is the Mid Drive 750W BBS02 to the point of being reliable

[Longhorngary]

I'm considering building an ebike and have read several threads including the BBS02 threads. It seemed this engine was plagued with problems at least early on, have these been addressed in later builds and would this prove to be a reliable engine if purchased from one of the recommended dealers and kept stock from the dealer.

Good question...I had also read reports of the built in controller being unreliable. Not sure if these issues have been resolved with all the remaining BBS02 currently being sold .....and theres always a chance that there is still " old stock" units, being sold as new, for a lower price, with these negative issues/ problems.

Wow , those are some pretty serious problems, for a unit that isnt inexpensive by any means.

I sure wouldnt like spending $500 on one , and then having those problems occur under average riding conditions. Now if someone was riding thru constant water, sand ,etc...I can understand some problems.

That is why you buy from Paul at EM3EV.com who has great warranty support (just in case you are one of those people who have a bad unit arrive).

For the price involved , I dont understand why there seem to have been so many bad units even sold. It would be different if these mid drives were priced low like the hub motors are { $200 and under category} . Evidently the units werent properly tested before being sold to the masses.

Naturally there is better options than Bafang.
But at a reasonable 250W Power (350W max from the same motor).
The BEWO KIT.

I doubt a 250 -350 watt mid drive would work well for me and my area. I weigh 230 lbs and many roads around here have steep long inclines. I also like the ability to do at least 30 mph on occasions , when travelling down dirt roads in my area.

You are just a dreamer.
Regular Bicycles are not able to handle your weight at that top speed.
You better start looking for a Honda NX-250 or similar.

Yeah. I am a dreamer...Ive only been riding a ebike , for the last 4 years, that I built , which pulls me at a top speed of 36 mph.

Looks like you and chalo have the same metal disorders..you believe your own lies and faulty conjectures.

Please provide ANY documentation or forum showing that there are as many BEWO units in use as there are Bafang. I can only think of two users here. And there are hundreds of 8Fun. How can you definitely say the BEWO is better without any facts?

Now, I admit it is and interesting design and a very thrifty price, but where's the data. Where are the users you are basing this statement on. So far it is only in advertising and the fact that BEWO has a steel ger. Gears are not failing at an high or even particularly noticeable rate. I have a cheap spare. I have several spares covering the parts that MIGHT be consumables in the long term use or high mileage. But only because it is cheap insurance. I wonder how fast we will get replacement parts from BEWO. Surely like every machine it has it's week spot Just that it is not yet obvious wit two users on the largest Bike building forum.

The biggest problem BEWO has going forward in AU or the USA is the need for speed and power. You are happy, and usually severely critical of those who don't want the anemic 250-350W rides you and I are happy with. I read a funny turn of phrase from Micah the other days. He refereed to a 36V 500W kit as a "beginners" bike. A few high number of riders on this forum are what I have come to respectfully call, power rangers. A term from their generation. But they are hungry for power and speed. It's what excites a growing segment of he market. Most of them have little or no interest in old dorks trying to learn their way into the hobby. They'll go on instantly about their beloved RC Lipo and don't want anything that they can't transform into a power house. I get lots of enjoyment watching their builds. Mostly because 40 years ago I'd be one of them

BEWO is their grandfathers mid drive, like my BBS01. BTW I hope to help a friend install a BEWO. I recommended it to him. He's like us. Happy with anemia. :lol:

Point any regular, unpowered bike down a long steep hill and it'll do 50kph and 100kg riders aren't that uncommon in a lot of places.

It looks like Kiriakos and Chalo are the forum masters at spouting out their arrogant bullsh1t claims and trying to belittle other ebike owners that dont spend a ton of money on their ebike purchases/ builds. Ebike snobs can be quite amusing.

If you prefer to ignore safety warnings this is your choice.
What is wise to do is to locate the manufacturer of your bicycle and make a telephone call to him, and ask his own opinion regarding your own plans.

I personally know of a 130kg rider that rides around on a "regular" bike without any issues - he even bought a cheap as chips bike when he was staying in China for a while and even that had no problems so I just don't know where you're getting your data from.

Kiriakos pulls much of his data, out of his ass, and presents his faulty opinions , as pure facts that are supposed to apply to everyone in every situation.

Hmm, I'd say that once you get past Chalo's opinionated bluster, there's actually a solid layer of experience to learn from. With KGR, there's just another layer of opinionated bluster.

FWIW, my BBS02 (purchased 7/14, from the first batch with the 9-FET controllers) has been problem-free for 2,500 km now. Kepler has posted similar reliability. Of course there is a significant bias toward posting problems vs. boring everyday usage, so I imagine there are many similar success stories. Might be worth contacting Paul at EM3EV to get an idea of the ratio of problems to units moved. Problems not related to jacking around the controller programming, that is.

I dont deny they have knowledge or experience, I claim they make way to many assertions and conjectures and try to present those things as facts . In this thread alone, we can see the evidence. They also seem to have a grudge against anyone that is happy with their inexpensive bike purchases. They often present their posts with a very snobish attitude, which I think doesnt help their cause.

Well is there a dependable workhorse middrive. I'm a larger guy and live in the hills and worried a hub motor may not handle things. I'm not looking for a speed demon, just a dependable motor to due the job. 20-25mph on the flats is more than fast enough for me. I want a bike to work first and foremost not do 35mph but has to be worked on every other day just to keep running.

I am 6ft 5" tall..weigh around 240 lbs...and my roads in my area are hilly.

From your above post, it seems like you may not even need a mid drive system .

I have been using a rear brushless hub motor, direct drive, for 4 years...got it off ebay..and you can get these kits for $195 shipped to your door.

I can go up all my hills, without pedalling , and if I do pedal with the throttle, the bike has no problem on these hills at all

Im using a typical lifepo4 - 48 volt - 20 a/h battery and a lyen controller.
