Dengfu E 82 in Gold-Color

to say their products are not finished is a bit rude no?

the current m560 and m510 work very well, but it is up to you how you build and setup everything. so user experience may vary.

like some users do not check factory bolt torque and do not put loctite but they do complain about loosing bolts...

especially in FW department and fine settings like PAS level adjustment there is room from improvement from the factory. i set everything myself and im very happy with these engines. but again it requieres some input from your side


like all stuff it requires some knowledge and skill to be happy with the end results and that is not for everybody...

DIY building is for people who like to tinker with their own stuff and not be reliable of others.
nobody talks about 'profitability' because we are not looking for profit.

I think most people here just like to spec their own bikes and have fun.

Myself i like to build bikes with specs you cannot get for the money otherwise. like my recent kunlun superenduro build.
yes it was 5K and it weighs 25kg, but if you compare specs you cannot get similar build specs in any of the big brand bikes

if you think you can please show me and i will buy it!
-carbon frame and wheels
-quality components rated for usage of the bike (e- enduro)

most factory build bikes have trail tires and basic trail suspension to keep price and weight down. but who wants that??!

even if you build an ultra light bike like cef50 with decent suspension and decent wheels/tires it will still weigh 22/23kg... because of components choices!

but an enduro with flimsy suspension and trail tires suck, yet this is what the whole industry is doing atm.

i have been using these motors for the last 4,5 years and never had any big problems.
the problems i did have were
- broken display because of an crash
- 1 broken bearing in my oldest m600 motor due to moisture ingress( which was easy to diy replace)

as i ride all year mostly in muddy wet conditions i think its fair to say it has turned out to be reliable enough for me.

biggest selling point of the bafang system is that you can service and repair it yourself which with many brands you cannot and you end up bring it to a lbs hoping they can help you within a few weeks... only be be charged an arm and leg for an software update or small part after 9 weeks of waiting

I see that you are not reading my posts again, but defending those who charged you for a semi-finished product.

and I wrote it wrong, it's not about profit, it's about the finished bike being cheaper than the bafang DIY.

i bought 2 m510 fc1.0 one rev1. second rev2! one of the first on the forum, I could not upgrade the firmware because rev1 and rev2 are not compatible.
the m510 itself has power, I'm writing about fc1.0, but there was no control, at the slightest pressure of the pedal it moved 100%.
I wrote to Bafang and the seller and never got a reply.
I also had an m820, the specs say it has rocky mode, I never got an answer how to activate rocky mode! in Boost mode there is an interruption in pedaling power, not a reduction but an interruption, and I never got an answer for that either.
No one can tell me that these engines are not a semi-finished product!
that means I paid for 3 engines that don't work as they should, they solve some problems with time. but what about those engines on which.a can't solve the problems?
Bosch is more expensive, but at least I have service support. most engines can be repaired, you just need to know how to buy parts!

That bike is 5000 euros, it's a good joke.

I am writing about the first version of the m510 engine! and he had a lot of problems. fc1.0 had v.1 v.2 we are not sure which fw is for which version. read on the forum about m510 motors. and as far as I know all electronic components and all products must be tested for the European market! from European institutes. and meet the regulations. all bikes you buy in the store have a declaration of conformity with European standards or the standards of a certain country.

is it so hard to admit that diy ebike is not profitable financially? I admit that in the segment up to 250w we call it "legal" is not profitable. if someone wants m600 m560 or a stronger engine then there is not much choice.

You are wrong on several sbjects.

1) EU certification is only an certification provided by the manufacturing company, that their product respect EU rules. Proved by selfmade internal testing procedure or by external certification company. Not an certifcat provided by an EU desk after test. I know that because i had taked time to verified at what coresponding the EU certification. Try to find where are done your EU certification

2) The alone difference with M510 rev1 and rev2 is the controller. You just need to replace it (+- 100 euro) to have an rev2. I know that, because i had do it. Wich major brand allow customer to replace controller in their motor ? which major brand build their motors since 2017 with the same fixing points ?

i believe you are the joke.
good afternoon to you and your problems

what are you trying to prove anyways?

now you have written what I am talking about. you paid 100 euros to repair the engine that is under warranty!


very clever!

I don't have any more problems, the team that drives Bafang remains in problems!

that engine was over 4.5 years old if you read but my post.

but that seems to be your problem.

instead of bashing something learn to develop your skillset so you wont have to rely on any warranty and cry on internet when resellers start ignoring you.

also my bikes have no problems compared to yours, thats why im
not crying and whining like a litle kid on the forums

Another some wrong affirmations

They don't work as you want. But other (me) are satified by their motor.

For the M510 i have said upper the answer. For you, no way to paid 100 euro to upgrade motor. For me that's integrated in china purchase, the develloping is done by customer and paid more to finalize using is an possibility, raison why i wait several months and return to purchase an new product.

For the M820, i had answer from bafang, the rocky mode is the boost mode and they have power cut if it become too hot, if you use it for long time (depend of you weight/legs torque/weather). I set my use to 90% for Speed+ mode, i never use boost mode and i'm fully satisfied by my M820

well done, very smart! you pay for the product, then within the warranty you also pay for the spare parts that should be paid for by the manufacturer, you are wasting your time and money! for the profit of Bafang, to whom you already paid all that! and Bafang has an annual profit in millions of euros.

hahaha you are very smart!

I started t enjoy this thread in the beginning but I can't believe you waste so much time and finger work to justify your cases.
Everyone just be happy with what there're doing and don't turn it in to a slanging match

I just admitted that I made a mistake with the DIY project and that it was too expensive for me.
the fact that some cannot admit it and have already spent a lot of euros is their problem.
and according to the reactions, they don't want to admit it.
and Bafang protect as if it were their company.

I'm sorry once again that I started writing that in this post.

nice greetings to everyone.
