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

Any feedback on this new gearbox from SRI, the 'archimedes drive': https://www.youtube.com/watch?v=zoaHeamUqBE Think this is any easier to manufacture (the one using ball bearings demo'd in the clear acrylic) or hold up to ebike abuse? Anyway, my kit has seen near-daily use for over a year without m...

Re: Cycle Analyst V3 preview and first beta release

A few more questions: - I need to extend the 'speedo sensor'. Is this a normal pair of wires or is it shielded? - In the 'battery config' screen, can I set a battery >99.0ah? Can I get an accurate battery icon without this matching my pack (120ah)? Maybe in a future release? thanks for the help thus...

Re: Cycle Analyst V3 preview and first beta release

Problem: My CA3 takes a long time to shut down. I have it in a 72v (20s) vehicle with two Curtis 1238 controllers, who's caps I believe are feeding the CA3 when I shut the contactor off. Is there a suggested way to address this? I've thought about inline resistors and optionally breaking the 72v wir...

Re: Have anyone tried using 4S Lipo on a 12V trolling motor?

I use a 24 V 80'-ish' lb Motorguide trolling motor with a Kelly 24 V brushed controller. ... As battery I use a 8S (24V) LiFePO4 70 Ah battery. But this could also be a regular series lead setup. I recently modified the trolling motor to be PWM controlled. What's a difference in battery does that m...

Main Contactor powered by DC-DC Converter ?

Hi. I'm building another 72V AC powered ATV/UTV thing using Nissan Leaf packs and would like to avoid using a 12V battery. Some setups I've seen use a DC-DC Converter with a switchable 'enable' wire (Sevcon's DC-DC, some Delta-Q chargers, etc) that will turn on the DC-DC converter when pack voltage ...

Re: Cycle Analyst V3 preview and first beta release

Is it possible to *input* information to the CA3 over serial? I have applications where additional information is needed and would really like to be able to have a custom field or ability to flash a text string to say the lower field of the LCD for X seconds.

Re: STIFF THROTTLE

I found spraying lithium grease in my thumb throttle quite helpful. The resistance was more with the plastic being poorly manufactured (like most Chinese stuff) causing internal rubbing - rather than a super stiff spring.

My Magura twist throttle was buttery smooth right out of the box.

Justin, Are there plans to monitor cell voltage and provide cell balancing anywhere in the future? Maybe support CAN/i2c/whatever streams from other cell monitors?

Dave and a few others have mounted their Tangent kits within the Triangle.

Another Hope user here (Pro II Evo) - no issues to date.

Also there's lots of talk about the noise of gearbox, but I think most people move out of my way on sidewalks and stuff because of the 'clack, clack, clack' of the hub as slow down :).
