Well, I guess Sizing is almost spot on to my Mondraker Crafty RR built as a 29er.
IMO the effective TopTube is even a bit shorter. I think they switched it up in this chart.
Taller headtube makes a bit higher stack.
Should be good in XL. Unfortunately, there is no data for size L. Maybe I'll import it.

The TT of the Crafty is much longer then CEF50, even if the reach value is the same. This is due to the steeper seat angle of the CEF50.

I THINK they made a mistake here...

This (red) would be the effective TT, which is shorter than the 670 of the Crafty.
Or do you mean that it is not the effective TT, because the scale (blue) is not perpendicular? Then you would be right, but the values of the Crafty and the CEF50 would not be comparable...

All correct- like written above. The effective TT of the CEF50 is 15mm shorter, due to the steeper seat angle. Imagine the seat angle is getting steeper, then the TT is getting shorter without any effect on the reach value..

I am going to build an m820 bike. Is there a FAQ of all the parts to buy? Also I would like to build a battery pack that is comprised of 6x 100wh subpacks so i can fly with it via TSA rules. Can the external port for the m820 can power the motor without the internal battery inside of it? Basically can I make my own range extender this way.

 

[mike_kelly]

You must replace the connector and rewire to use an external battery to power the motor. See my thread on the subject.

Thanks guys. I will carry it because it is lightly finished. Work hard. I used to ride the E10 L size, but the CEF50 is small. I may exchange it for an XL size. It is very good that the seat angle is happening

View attachment 121430 Do you know the RAD measurement of the size L?

How tall are you?

 

[ficorama]

I finally finished installing the 720W internal battery without the case. The weight of the bike is 19 kg. A lot of mounting foam will warm the battery in winter. Size M

honestly, not much of a weight score! on e10 xl size, if I fold the 720wh battery, put lighter components, lighter tires, lighter fork, wheels...... I believe the weight could be under 22kg. and much more power. and in m size even lighter.

Hey! Nice build!
Which spider and chainring are you using?

 

[ymmr32]

How tall are you?

Hello. I'm 173cm tall and prefer big frames. My custom hardtail has a reach of 538 with a seat angle of 80 and a stem length of 20mm. I want the reach of the CEF50 to be about 20mm longer.

 

[ymmr32]

Hey! Nice build!
Which spider and chainring are you using?

Hello. It is a genuine spider of m510. I stripped it of paint and polished it silver. Chainrings are cheap Chinese ones. It is PCD104.

I have a question: On the DP C245.CAN I tried connecting into Go+, which I wasn't expecting it to work at all. However, my phone found the DP C245.CAN right away and paired with it. Then it seems like it disconnects and throws up in the middle of the phone screen a connecting message that doesn't seem to go away.

Have you guys figured out the fix for this?

 

[mike_kelly]

The general consensus is that there is a third version of the unit and only it works. Part number listed as XXX.V3

Yea I have that version, but it gets stuck after successful pair on that connecting screen.

 

[mike_kelly]

I would try a different phone if you have access. Note the version of Android on each to see if it makes a difference. Same with Bluetooth. Good Luck

Thank you for this information!
Is there a list of Go+ compatible components?
Before I order I want to make sure to get the "best" parts...

 

[Myalteregohamish]

I just looked and it’s this version.

Ahn, y

I just looked and it’s this version.

Ahn you lose. We have some lovely parting gifts, thank you for playing
Linda tells me that she can't get the 3.0 version and she is getting no info as to when they might be available. But there are a few out in the wild shown in a thread here on EMTB.

 

[mike_kelly]

Barb went for her maiden ride and loves the bike. 39lbs with mostly budget parts.

There is very little info on GO+. You can find the manual on Bafangs site but it is of limited use.

Are you able to do 28mph on the motor?

CEF50 reach is 483, E10 size L reach is 485 - almost same. The difference is the toptube length, 630 vs. 658 for the E10. This is related to the steeper seat angle of the CEF50, so I assume the seated position feels short for You. May be You try to move the saddle backwards as much as possible, or look for a dropper with more setback…

 

[thaeber]

honestly, not much of a weight score! on e10 xl size, if I fold the 720wh battery, put lighter components, lighter tires, lighter fork, wheels...... I believe the weight could be under 22kg. and much more power. and in m size even lighter.

Easy to calculate, CEF50 vs. E10:

- frame is appr. 1,5 kg lighter
- battery is only 0,5 kg lighter
- engine is 0,6 kg lighter

Summing up to weight saving potential of appr. 2.6 kg. If You use a lighter battery (LAnton) You’ll save another 0,7 kg.

can change with besst tool, and also with 38T chainring to reach that speed on flat terrain.

Haha, I’ll take my KFC gift certificate. Yea I found the thread where this was being discussed and it looks like at the earliest it theoretically be August. Huge miss on the part of Bafan.

I noticed the motor going downhill will still give you power well into the 20’s which gets rid of that feeling like all of a sudden you’re being dragged backwards.

 

[Myalteregohamish]

Are there any displays that work with our motors that also work with GO+?

When did she tell you this?
Just a couple of hours ago she told me:

and we can give the DPC245(3.0)version which can use “go+” app.( fyi attached picture), thank you very much.

 

[Myalteregohamish]

Just a couple of hours ago she told me:

I asked yesterday and she (Linda) told me August. Who told you, you can by version 3.0?
