    Controller seems to be stuck in regen mode?

    Here's the story - Was not able to program the regen on Lyen 18fet HV controller, it was set to engage whenever throttle was released. So, I disconnected the regen jumper and it worked fine - except no regen. Then I thought of running the regen jumper through one of my e-brake levers, it worked...

    Throttle wiring question

    I am hooking up a 3-wire throttle, Red-White-Black to a infineon controller Red-Green-Black. Do I hook-up the white throttle wire to the green controller wire? I thought I read somewhere on here 'but can't find it now' that you have to hook it up as follows Throttle - Controller...

    Strange lipo problem- 1/2 of battery weakening

    For the past month, I have noticed that all of my 6s batteries are getting weak on 1 side. Cells 1thru 3 charge up ok and cells 4 thru 6 are dying. I run 24s, and it seems the 1st and last battery in series discharge more than the middle 2. At first I thought it was because I was bulk charging...

    controller to motor wiring problem

    Hey Guys, I am trying to hook-up an HS3540/R5303 motor to a Lyen 18fet controller. I have tried all 36 combinations of hall & phase connections. In 2 combinations it starts forward noisily for about 2 seconds and then stops, if I wait a couple seconds it will do it again. I disconnected the CA...

    3rd build- Custom FS Longtail (New & Improved)

    I want to thank all you guys who have gone before and paved the way for e-bike progress. I am not doing anything extra ordinary, just trying to improve my own riding situation. For the most part I have been happy with my present set-up except- (1) too much weight on rear rack (2) no disc brake...

    cor-ten steel for frame material?

    I am in the process of designing a frame for a new bike. I have decided to go with steel instead of aluminum, because this will be my 1st welding job. I have been looking for alloy steel angle stock to work with. I have researched available supplies to find 1" x 1" x 1/8" or 1 1/4" x 1 1/4" x...

    Would you ride with 1 missing spoke?

    Over the past several days I have noticed the creaking & popping noise getting louder on my 'drive wheel' whenever I turn to the left. So, before I took-off today, I started tightening up some loose spokes. 1 snapped right at the nipple before it even began to tighten. The wheel is pretty...

    "movin em forward" custom battery case

    Not being able to keep the front tire on the ground while accelerating encouraged me to start this project. I 1st thought of strapping heavy weights to the front fork and realized that was stupid. So here's what I did I used steel pop rivets to attach the brackets to the framesketched out the...

    Controller "stutters" on Fast acceleration

    I have a Lyen 12fet 84-132 volt controller running on 24s that accelerates fine under 'no-load'. However, when I am riding it will not accelerate smoothly under hard throttle. It will accelerate up to full speed if I ease into it. I believe I have it wired up correctly - the motor is a...

    E-bike Roadkill? No, just Roadstunned

    Well, I knew it was gonna happen eventually, I hit a squirrel. I was going about 25mph and barely saw it before I felt it jolt my front tire. I slowed down right away and did a u-turn just in time to see it get up and scamper off the road. Another reason e-bikes are "enviromentally friendly" 8)

    E-Bike Discrimination & bicycles too

    I was over in the "rough side" of town yesterday helping a friend fix his scooter- it's a gasser, but that's beside the point. We were gettin hungry so I went in search of some fast food. Navigating my way through the junkies and crack whores I spotted a Taco Bell, there was nothing around there...

    cheap dependable power supply

    Last night, after burning up my 3rd one of these - http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6256 - in less than a year and seeing that they are on backorder at HK, I went online looking for 12 volt power supplies. I wound up getting a 500 watt 12volt computer power...

    Lipo Abuse? Still Usable?

    A couple days ago I was reconfiguring a 24s 1p pack into a 12s 2p pack w/ 6s 5ah turnigy's and paralled 2 to 1 for about 15 seconds. 50 volt to 25 volt. I should have payed more attention because it "sparked" with no load. The batteries got extremely hot very fast. I have recharged the 2 that...

    End of the TEST - 9 Continent - 2813 miles @ 99 volts

    Usually 99.4 or 5 hot off the chargers to be more precise. Powered by 24s2p lipo and channeled through an 18fet 72volt 65amp Lyen controller, the motor can get rather toasty after a 7 mile suburban sprint keeping up with 40 mile an hour traffic. I have thought about drilling holes in the side...

    Better rear rack for full suspension bike suggestions

    I have been trying to find a rear rack to hold 30 lbs. If there was one that would attach to rear axle and have supports to attach to rear triangle w/brackets - it would be ideal. I have looked at "old man mountain " & " pletscher." The pletscher looks pretty flimsy and the "omm" has a system...
