Re: Feiwel 27.5+ Bafang M600 Dual suspension emoutain bike

Geometry looks pretty shaky
I agree, the geometry looks very long and steep. Also another gotcha, is whether they use bushings or bearings in the rear linkages. they don't always use bearings by default.

I'd pass on this one.

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

Hmm I can't see any reason why the battery will have any impact on the use of a throttle. It is true that the battery will have CANBUS and UART connections and +5V for a total of 7 pins, Maybe the Throttle is getting the +5v supply from the battery...

yes I as referring to the battery in the video. it looks like this one: http://www.reention.com/product/detail/47 which is nothing like the internal bafang battery BT F03-450 EN15194 is the European standard for Pedal Assist Bicycles (PAS).

That's not the bafang battery it's a battery like Frey use..

I heard that Bafang were making changes to the battery to comply with EN15194 and that November they will have the batteries available.

Re: Carbon Fiber e bike with Bafang M 600 mid installed with throttle

I visited the Enwe factory in China and saw this bike. looks good, I did not get to ride it though as it was a 3D printed model prior to them finishing the mold. It is the same as the Dengfu bike..

Re: My Bafang Ultra Mountain Bike! Frey AM1000

Where did you read this? I'm interested to learn more. I think the EX1 is a great concept. Strong, simple. Etc. Double shifting is a problem with 1x11 or 1x12. Who really needs 11 gears on an ebike.

I don't think you'll get the M600 motor and battery for $600USD.. Pretty sure SRAM EX1 is > $200USD as well... otherwise let me know where you're getting them and I can buy mine from there. But yeah you're correct, it's not a cheap exercise, but cheaper than big name brands, with hopefully equal qua...

Re: Dave's 80:1 RC mid drive kit build log

well it's funny but when i first asked the question, before I saw that you tube video, it was actually the sound of the drive that first got me thinking about the similarity between tangent and TQ..

Anyway, it is nice to see various solutions to the reduction problem, all with great success.

Re: Dave's 80:1 RC mid drive kit build log

slightly off topic. Do you know about TQ motors that are in the new Haibike Flyon? do you think they use a similar gear reduction to yours? I watched a vid, and it sounds 'similar'..

Re: FREY eMTB with Bafang m600 is developing with your ideas!

Id like to know if it really will be less nimble. It's only 10mm? Can anyone actually confirm after riding say a 475mm chain stay. Then jumping on a 460mm chain stay if there was a significant difference. I rode the eOne Sixty Merida and it was a wheelie machine. Very nimble but 439mm chain stay... ...

Re: FREY eMTB with Bafang m600 is developing with your ideas!

Turbo levo is 459mm RC length. This is 460mm which seems pretty good to me. I've seen many of the to brand name bikes anywhere between 440(Merida eOne sixty) up to 475mm (haibike) most between 450 and 470 though. I think it will handle just fine. It's not like it's super long like 530mm or anything....

So the controller is not turning off? I misunderstood. Will it could be a poor joint. In one of your connectors. See if you can measure the backs of the connectors with a multimeter

could be a single dead cell in the pack, causing the Low Voltage Cutoff on the Battery Management System to cut power to the entire pack. The battery voltage will read high (because most of the cells are still good, but that one bank is low.. Example for a 10S pack could be: 3.5, 3.5, 3.5, 3.5, 2.6,...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

check the hubs for loose bearings, we bought some ebikes with Novatec hubs, and they were not particularly high-end, anyway, the slack in the hubs' bearings would deform the cassete alignment and result in chain jumping issues. New quality hub and cassette and problem is gone, with all of the identi...

Re: Electric Surf Board

I don't understand this. I thought controllers had current limiting. Therefore really they should never fail unless there is a manufacturing defect or reverse polarity or something.

Anyway, good luck.
