Re: Tangent Motors RC mid drive kit

Another little update for anyone pondering the IGH question: Will they hold up to the power? I now have an Alfine 8 set up and test rode it for just under 20 miles offroad today and what a different experience it is...held up fine to today's riding and hopefully many more miles. A much easier and s...

Re: Tangent Motors RC mid drive kit

Video soon.... I am looking for more speed than my current gearing offers (39MPH) me and am undecided as to which sprocket to swap out for best results: motor output to bigger or... crankset motor receiver to smaller or.... crankset chain wheel to bigger.... three ways to get more speed but not cer...

The standard kit uses a CA to process the throttle signal, so just like with torque sensing, you can use anything the CA supports.

Re: Luna Cycle front & rear lights

No, none of the lights (at least as of when I bought them) had any extended functionality whatsoever. Probably the biggest missing feature. You could probably wire your own blinking circuit in series with them without any difficulties.

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

Can confirm, this drive will happily climb trees all day long in low gear. Or just flip you on your back, if your throttle response isn't tuned down enough.

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

If you ride on flat land, and feel the need to quiet down a bit you could drop your chain to smallest cog on the rear and ease up on the throttle. Dave, is this thing fairly quiet at moderate RPMs when it's under heavy load? What i'm thinking is if I'm on a steep section, say 25-30% grade and there...

That's odd. The Castle Creations documentation for the Phoenix Edge HV series states that a maximum of 12s is supported.

Anyone have experiences to report using the Phaserunner with an Astro RC motor? I am running it with a 80-100 motor in a scooter. It was a total bitch to tune, as the motor is so small... My tune still cuts out every once in awhile from "phase overcurrent". While I LOVE the controller, I would only...

Re: New type of power transmission

Castle Creations RC controllers work just fine in ebike applications. I'd still favor Justin's FOC unit if you're confident you can set it up to handle your motor, but RC controllers aren't all going to burn up.

Luna Cycle front & rear lights

A few months ago I purchased a Luna Cycle Cyclops (with button, regular brightness) and rear light for use commuting in the dark of winter. The bad: Handlebar mount for the Cyclops is very wide-diameter even at its narrowest configuration. Be prepared to shim heavily. The Cyclops is bulky not very s...

Re: A good quality full twist throttle ??

The Domino 5k throttle looks pretty nice compared to the de-facto standard Magura. I'll probably upgrade to one of those myself someday. See https://evmc2.wordpress.com/2014/03/30/ ... vs-magura/

Re: Taking Charge: Let's Develop the Products That We Want!

Good-quality motors, controllers, batteries, and sets of bike parts can cost several hundred dollars each at that power level. Prices are dropping, and DIY ebikes (read: no overhead costs) such as are common around here can easily halve the price of comparable commercial offerings, so it's definitel...

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

On the subject of chainrings, I like the 38t narrow-wide (from RaceFace) I'm running as it gives me enough leverage to still pedal up a hill if I'm inclined to. I only wish it came in a nice hard steel. Limits your top speed on a flat to under ~50kph, but a larger motor freewheel could address that ...

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

I'd love to hear what it sounds like at 500-1000w, If it can be pretty quiet at those speeds then I would have no issues passing people "quietly" at low power and still have another 1000+w left to play with when im out away from the other bikes and walkers. The noise is really proportional to the R...

From the name and the number of wires it looks like it's meant for use with a brushed motor. I don't know if you can even get those for ebikes any more.

Re: Lurchy Power Limiting - way to smooth it out?

Make sure you've followed the CA guide to disable all speed limiting. That caused extremely jerky response on my bike until I caught it, even though the limit was theoretically really high.

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

I've run it around 35A for minutes at a time with the 3210 and things merely get warm. It's efficient enough (and my chainring is small enough) that it can be difficult to actually push the motor harder than that without a good hill.

So start from standstill will be smooth like a hub with that ESC? I mean if the position of rotor is known there should be no stutter or rattling at take off?

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

It's been said plenty before, but I'll repeat that this kit has so much torque that you'll easily do a wheelie from a dead standstill if you aren't in a high enough gear. I also do start-stop commuting on the kit, including starting from nothing in top (38:11) gear on hills up to 20%, and the only t...

So that's why Castle Creations ESCs are so tiny compared to conventional ebike controllers! I was wondering. Does that mean it might be safe to use a "conventional" bulky controller such as the Grin Tech Phaserunner at higher-than-rated continuous power, if those ratings were made with low-RPM motor...

RC ESCs may not be designed for ebike use, but Castle Creations controllers such as the HV80 have been in use for years and nobody seems to have any trouble with them.
