Re: Townie bicycle is getting too many compliments - Uglify

Some of the best "ugly" bikes are by design. Around here, there's a million Google bikes (aka clown bikes) sitting everywhere not locked and free for the taking. Image

Re: Re locking my bike battery

I've been building aluminum box panniers that will be lockable via BluetoothLE and app on iPhone. The battery pack will be mounted and riveted at the bottom of the pannier in it's own box. I designed it this way so that the pannier box would serve as one big heatsink and the $700 Luna battery pack i...

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

Again, the Astra motor polls overlap one another. I'm betting that that is why the phases will interact and give an incorrect back EMF signal on an astro motor. Matt, it's not that the Astros are incorrectly wound or give off bad signals. It is the plain fact motors and controllers are very basic s...

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

NTCE is willing to produce the ISIS version in the correct spindle length to fit the kit (we need 30mm of spindle stickout on the chain side, plus 6mm to accommodate the mounting brackets, their existing dimensions aren't compatible with the freewheel crankset). There would be some costs associated...

Defeating this one is easy. The bad guys can just use what they're likely already carrying- pliers or a clipper. A quick squash or cut and this thing would be disabled. I'll take mine hidden.

Lightrush, Thanks for the updates! I too am going to do a Tangent PAS. I've a few questions for you: I've been looking at the 136mm spindle Thun and have been unsure if that'd work even though it's longer on one side. Which Thun did you use? Is that gear sensor doing anything for you? I need a 130mm...

Re: INTENSE Tracer 275 with Tangent Ascent

Lowering the cadence from the motor to the cranks is good for making your input more real/useful. But it will mean you will be running in smaller cogs in the back, causing more drivetrain strain/wear. That is why I would prefer a double freewheel on the motor to separate the cranks-to-motor ratio f...

Just FYI http://www.ncte.com/standard-sensors/pedelec-sensors/ I took the time to contact a NCTE rep and here's what I found out: - they are the OEM for Thun - the shafts are hollow (not sure if this impacts durability in our use case) - they do not offer spare parts so if you blow the bearings, it...

Re: INTENSE Tracer 275 with Tangent Ascent

The 18650b pack is only 2lbs lighter than the corresponding 25r pack. But we could fit two 18650b packs in about the same space as the 25r pack, so 2 in parallel is enough current and 40Ah of fun. From Tangent specs, the Ascent needs (can do) 1750w, 35a, 50v continuous. From Luna specs, that Panaso...

Dave,

To help us with gearing properly, do you have a number for stock RPM or cadence at 100% throttle?

Oh nice find! Pretty much everything I'd wish for in a BMS except that it's for Android only (no iPhone), and supports smallish series lengths.

I would rather they dropped the whole thing and would let us get all needed info on our smartphones via an app. Then we could get all kinds of data logged too, right into the app. And we could display things they way we feel like, change info when needed and do all settings from our smartphones.

Re: Adaptto Mini-E/Max-E Owner's ALPHA TEST Thread

@Scott I'd think Adaptto would have the screen in your 32s BMS picture as a summary screen. One could easily fit a LOT more info in on that screen by removing white space (e.g. white lines between the bars). That'd mean it'd be good for a quick look but you'd have to go elsewhere for details (which...

Surprised nobody's asked this yet. Do we have amp and ohm numbers for the three controllers (max-e, midi-e, and mini-e) so we can model each in the ebikes.ca motor simulator?
