    preferred throttle style for indirect steering tadpole ?

    I've tried various options for throttles and found to use a left hand half throttle at the left handlebar of my tadpole trikes and velomobile is the most convenient. While the right hand is occupied with shifting, rotating the left hand to power the motor becomes natural quite quickly. When...

    Oil cooling a motor with transformer oil/dielectric fluid - the next frontier?

    Really? You guys still discussing alternative oil for geared hub motors in 2024? Whats wrong with ATF? I hate the smell of ATF like the next guy (only jet fuel smells worst) but ATF has the right viscosity and got all the necessary additives (foam inhibitors, friction inhibitors, etc, etc) to...

    Run two motors on one controller? Maybe?

    Short answer: No. No matter what ingenious idea you come up with, it will not work. Get a second motor controller.

    is geared hub motor feasible in a 20-inch rim?

    If you use "Semi Recumbent", the Motor Simulator computes results much closer to measured real world data with a tadpole trike! ;)

    is geared hub motor feasible in a 20-inch rim?

    Yes its feasible. The small "250W" geared hub motors don't last long at these speed/power levels (BTDT), but the bigger "500W" geared hub motors can take it (Bafang CST, Grin V2, etc). Especially, if you use some 40-45ml ATF for cooling and lubrication of the internal free wheel clutch. If you...

    Your Whours for kms

    Milan GT Mk2 velomobile, MXUS 3005 RC, two 20s batteries, Phaserunner v1: Real world numbers from the CAv3 at 8°C on open country roads from city to city with light traffic: -at ø61,8km/h it consumed 0.996kWh/100km (130km distance, max 1.5kW, respecting speed limits, max 93.1km/h) switching...

    SURVEY: Your watts at various speeds

    The Milan got updated with a MXUS 3005 RC in 26" rim, custom 11-42t 10-speed cassette, 45/72t chain rings, a new 20s/2.3kWh battery made from 21700 5000mAh cells and is shot with reasonably quick Conti Contact Urban*. Real world numbers from the CAv3 at 8°C on open country roads from city to...

    The Cycle Satiator, universal charger for the enthusiasts

    max 5A. That was the max Ampere my 7205 was putting out and IIRC its quite clearly stated in the specs and manual (max 103V, max 5A, max 360W). "7205" should give a slight hint, as well... ;) btw, thanks Amberwolf for clearing things up!

    The Cycle Satiator, universal charger for the enthusiasts

    I'm using two 48V Satiators (combined with other 36V chargers if needed) in parallel every day for several years, now. It just works. At the end of charge, one Satiator will reach end of charge about 0.1V before the other, though. the two Satiators are bolted together. The rubber O-rings...

    SURVEY: Your watts at various speeds

    Yeah, I've got a MXUS 3005RC DD hub 'just in case' waiting to get laced-up, but I'm still not entirely sure if it finds its way into the Milan. The new features of the Phaserunner could take care of the motor drag, though. I'll have to see how the Bafang CST will hold-up on my new commute.

    Nope, you are right. Since Tek left, this forum thread is way less useful.

    Your Creation's Before & After Pics

    On open roads without frequent traffic lights, I think its closer to 5.8 or 5.9Wh/km and it currently got a relatively slowish tire at the rear wheel (Big Ben 50-559). I have to do some further testing, but with some light pedaling (75W), 3.3Wh/km @ 40km/h, 4.5Wh/km @ 50km/h and 6Wh/km @ 60km/h...

    Your Creation's Before & After Pics

    Hehe! Since the view would by slightly restricted... ...and the Spandau's degrade the aero propertys, I think an extendable mini-gun turret in the back would be preferable. It would also cover my six quite nicely. :D

    Show me your electric velomobile.

    Starting with an old Milan is kind of cheating, don't you think? :D The Milan needs about 750W mechanical power to reach 100km/h. Realistically, thats at least 1kW electrical power at 80% hub motor efficiency. My guess, at these high rpm the little Bafang is a good deal less efficient (eddy...

    Show me your electric velomobile.

    Impressive, isn't it? On my first ride after the conversion, I could hardly believe the low consumption figures. Even setting everything to max and riding through the city with frequently starting from traffic lights, it only consumes 1/3 of my trike. About 86 lbs with hood (without battery...

    Show me your electric velomobile.

    Its a simple cadence sensor. If I want a workout and put more force to the pedals, adding assist power as well seemed wrong to me. On the other hand (since the magnets for the cadence sensor are mounted into the chain ring) by shifting down and raising the cadence for climbing hills, or by...

    Show me your electric velomobile.

    Yes. Its fully suspended. All Milan velomobiles have front suspension, but you can order them with or without rear suspension. I've changed the suspension from springs and friction damping to elastomere and kept it fairly stiff, though. Also, to eliminate the fairly strong brake steer, I've...

    Motor: currently a stock '250W' Bafang SWXH 26"/36V version with 9-speed 11-32t freewheel and Shimano 105 derailleur. Cranks: Patterson Metropolis 2-speed crank drive with 36t chain wheel (58t in overdrive). It allows me to pedal up to its 75km/h top speed at about 120 rpm. The Teflon chain...

    Finally, I can resurrect this old thread from the dead. ;) This is my take on a electrified velomobile: A Milan GT with Bafang SWXH, Phaserunner and 20s battery.

    Cycle Analyst V3 preview and first beta release

    Bug report! ;) I've updated from FW v3.12 to v3.13x1G today (checked all the settings and had to correct some). So far, all good, except the max speed value has no decimal dot. It reads 654km/h (my trike is pretty quick, but not that fast :D) I'm not entirely sure if 65.4km/h would be the...

    Compact Field Oriented Controller, ASI + Grin, limited run

    Hi Grin Tech, Since the maximum regulated current available to power external accessory devices from Cycle Analyst v3 is limited, I was wondering if my Phaserunner v1 can power the hall throttle, 3x hall brake sensors, PAS, etc (drawing between 25-30mA combined); if I use a 74V (20s) battery...
