    Any info on a headless interface for a BBS02?

    Hi all, I'm in trailbike nirvana with my Banshee spitfire with a bafang BBS02 and small 12s 5000mah lipo pack. I've ridden a few levo's on the same trails and the experience is very similar despite the PAS. I found that by very carefully tuning the speed Vs current settings I can match my...

    Cadence Sensor Bikes

    I'm in the same position, I wish that Bafance would incorporate a torque sensor in this BBS unit already. Anyway, I've come across guides that describe how to extract the most from a PAS system like this to improve the ride ability, particularly on mtb trails...

    For all those still interested in good frame options, this is the direction I'm taking. It's one of the neatest least conspicuous enduro like builds I'm seen on a really good frame, an early Santa Cruz Nomad. Thanks for all the advice thus far. I'll post a few pics when I'm done.

    Thank you for pointing out that the BBS HD is heavier and just not necessary, you're absolutely right, I need climbing power and not speed. I've done a ton of searching looking at frames that are available here and I think that I've found promising options. The Transition Patrol and Smuggler...

    I'd like to build the perfect trail bike...

    Thank you Wayne for your very useful advice fine tuning the bafang. I've found some articles describing how to improve the control and it's looking more promising. I think that I'll have a go using a BBSHD on an enduro frame, it's worth a try without spending a fortune. Thank you all for your input.

    I'd like to build the perfect trail bike...

    Thank you all for the input. I've exlcuded the Bafang entirely because it doesn't have proper torque sensing. I have lots of high powered Astro ebikes posing at bicycles, it's fun for getting around but it completely destroys the feeling of cycling through forests silently and without killing my...

    I'd like to build the perfect trail bike...

    Thank you for confirming my thoughts on this. Hopefully somebody that's ridden a Levo and an ascent could perhaps chime in on the merits and riding experience of the two. Does anybody have any experience with the new Ascent PAS system? I've excluded the Bafang because as I understand the...

    I'd like to build the perfect trail bike...

    Hello all, Firstly, thank you for the excellent ES community sharing knowledge and innovating so freely, we are all grateful. I'm longing to build the perfect trail bike for attacking single track adventures. I have a few turnigy/Astro direct drive MTB and commuter bikes under my belt which...

    Stuttering Infineon Controller....

    Very interesting, thanks for the link. The auto hall sensor learning feature is not something I completely understood until now. The controller I have is the same board that the Lyen/EM3EV and e-crazyman sellers use as a basis for their controllers. I'm not sure what it's colloquially referred...

    Stuttering Infineon Controller....

    Hello Chaps, I have a stuttering issue with a 6 FET Infineon EB306 controller, I'm wondering if somebody might have any insight into the cause. The symptoms are severe stuttering under load, but perfect operation under no load. I've tested the motor (Astro 3220) and halls with a spare...

    non-pedal GNG 4kw

    Thanks very much for the explanation crossbreak. I haven't seen that spreadhseet you used for calculating chain forces before, looks excellent, is it available somewhere? One question - do #35 and #219 chains work well at small tooth counts because the rise-fall time of the links is short due...

    non-pedal GNG 4kw

    "9t bycicle sprocket will kill your final drive chain in minutes" That's an interesting point - do you know why that is and is it a function of chain pitch? I'm working on an ebike with 10T driving a 32 tooth 1/2 x 1/8 chain which from your statement is going to be a killer. I notice that #219...

    Bzhwindtalker's Blue FR (GNG mid drive)

    Very impressive ! How is it that your rear freewheel and chain for that matter holds up to these power levels (and torque). Is your hub anything special?

    Low power full suspension test setup

    Hi Roel, Absolutely great execution, your fabrication looks very impressive. I've been thinking about rear belt drives for awhile now, the whirring noise a chain makes while freewheeling gets annoying after a while. I'm guessing that you have a one-way bearing in the output gear to the...

    Sensored Turnigy GT Peace + vid

    Thanks Mike ! :D I look forward to seeing your bikes soon, especially with the 3 speed Rhs drive although even I'd feel a bit unsafe above 60km/h on a bicycle. It was however my original intention to go that route for which I ordered the TP packs freewheel adapter. After pedaling about with the...

    Thanks for compliments LFP and Thud :D :D ! This bike has me grinning every time I ride it. The infineon is an order of magnitude better than any open loop sensorless controller, it's just that from standstill, I really have to concentrate to stop the thing from wheeling. Once I'm going it's...

    Sensored Turnigy GT Peace + vid

    Thanks for the positive comments guys. AJ, I do think that a clutch would be solution for take off, although I'm hoping for an electronic solution. My next bike is going to be less commuter and a lot more offroad, I think that a slipper clutch will then be a must when landing jumps etc. Gwhy...

    Sensored Turnigy GT Peace + vid

    I've played with the phase current and it does indeed help but I find that it tames the entire response so that I lose that instant wheelie power that I now enjoy. What I'd really like ...dare I say it.....is a soft start for the 1'st few hundred rpm. I've tried that speed switch but I find that...

    Thanks gwhy, although I'm still moulding a glass fiber inner frame covers to hide the battery pack and motor. You guys deserve the biggest nod, I'm sometimes staggered by the level of engineering and sharing on these here forums. I did however forget to tip my cap to the head honcho Miles from...

    Hi, I've finally (it took a long while) got this bike moving under its own steam ! It's the GT Peace 29er with a Turnigy 130kV motor. I've got my take on a 4:1 belt reduction to a disc brake adapter ( thanks Matt) left side adapter with a 160mm disc brake. The disc is offset by 8mm to clear...

    son inlaws first play on a e-bike :-)

    Hmm. thanks for the tip regarding the current ratio. I'm not sure that I understand this relationship completely as yet but I do have mine currently set to 2.5 which I picked up from the hub motor guys. It's pouring with rain today but I'll give a 1.5X ratio a go later. Do you have a build...

    son inlaws first play on a e-bike :-)

    Well put together bike! I hope to get to a point soon that I'm confident enough with my build to send it off for wheelie practice. At the moment, the throttle sensitivity is such that anything but the lightest touch on the throttle sees the rider head over apex. I'd be keen to hear about how...

    Giant NRS/Mac hub/48v Headway now A123 build

    Excellent looking bike thus far. Those DNM forks looks very interesting indeed - especially the adjustable bridge that could possibly even accommodate a 29" wheel ! Thanks for the pics, the geometry and stance look perfect, it's spurred me into using my NRS frame as a basis for my next build.

    Apologies - I've gotten lost in the thread. I was asking the owner of the NRS :D

    Giant NRS/Mac hub/48v Headway now A123 build

    Hi Mark, I've been looking at an old NRS frame that I have and wondering about stick a triple clamp fork on it for a nice offroad electric - I'd love to see pics and get details on your fork to see what the geometry looks like. Cheers.
