    Catrike Expedition Touring Trike

    Nice trike. I like the extra cargo space in back; was that accomplished with an Xtracycle Freeloader? Eric

    Why did you get into electric bikes?

    I tried a colleague's ebike while at my previous company. I was interested, but the 9 mile ride was short enough to make riding a standard bike justifiable. When the company closed down and my new job was 20 miles away, I had to find a way to speed up my riding. Now my commute is about 50min by...

    Iovaykind's Novara Method 1.0 Build

    You can find these in most decent hardware stores. As dnmun stated, add washers to spread out the force. Eric

    Your experiences with headway headquarters - good? bad?

    I've had one experience. I arranged via a phone call to pick up some bus bars and plastic spacer blocks on my way home from work. The parts were set out and waiting for me when I arrived. Simple transaction. Seems like a small operation run by helpful folks. Eric

    Any recommendations about a durable tire/tube combination?

    The only thing that stopped all my flats are the super thick slime tubes. I've had bad luck with punctures on my 20 mile commute and these tubes have saved me from road side repairs at least 4 times. I have found the thinner slimes also work, but tend to be more puncture prone and do not re-seal...

    Pusher-Trailer: A Bicycle-Frame Solution

    Hello Kingfish, I have an Adams Trail-a-bike and used it with my youngest (probably 60Lbs at the time) for longer bike rides. The trailer's seat post mount stays clamped to the tube and allows easy removal of the trailer. There is a U joint on the trailer side of the mount to allow horizontal...

    What's Causing Excessive Current Draw?

    Thank you, all, for your input. LFP, I wondered about the throttle, especially since I park my bike outside, uncovered during the day while I'm at work. This has been a very wet Spring. It would explain the 36A/motor shut off symptom, but not really Symptom 1 where cycling the controller switch...

    What's Causing Excessive Current Draw?

    I'm having intermittent problems with my system. Symptom 1: CycleAnalyst indicates high current (2-10A) when the controller is first turned on and the bike is stationary. Normal is <1A. Resetting the controller using its power switch drops the indicated current by about half upon each toggle...

    Tidal Force S-750 Build by mikeross

    Mike, I don't want keep harping on fenders, but, as a fellow wet weather rider, thought I would share my experience. I used a front SKS like what you have and found it completely useless above 15MPH. The front tire picks up water from the road and throws it up and forward. Problem is, there's so...

    16-20 Mi w/4-33amphr SLA 24V 500W motor? help!

    I think the real answer is "it depends". You should consider: How fast, how many hills, how much stop & go, how hard will you be peddling and how quickly do you want to accelerate. My usage is about 6-8Ah from a 48V A123 pack during my 20 mile commute to work. My total elevation change is about...

    Testing the big 15 and 20Ah LiFePO4 cells is tough! *Pics*

    LFP, I agree with Camlight's suggestions for circuit reconfiguration, although I think he understates the potential problems from switching the gates directly through those inductive, leaded resistors. I would bet it's not the switching frequency, but the edge rates (high harmonic content) and...

    What batteries are you using?

    I'm using a 16S5P A123 pack assembled from 8 DeWalt tool packs. I purchased them from ebay tool pack sellers berchent & Your_Tool_Cage for $100 each about 10 months ago. I connected these to an ecitypower 45A BMS (~$45), and 75A discharge + 45A charge power poles. Total cost was about $900. The...

    Stuck, and had to call for back-up?

    Been there twice, both times due to flats. At about 200 total mileage, and 9miles from home, I ran over something metal with my back tire nearly locked up for a panic stop at a red light. Thought I could make it through the intersection while the light was still green. Not sure what the object...

    RealForce LiFePO4 packs (10ah 24-36v)

    His quotation states, "Twenty (20) units MOQ ." MOQ = Minimum Order Quantity; that's probably why you did not receive a response for a lower number. Do you have any information about the C rate of these packs? They all look like 2C except the tool packs here. which are 10C. Eric S.
