    The Battery or is it the Controller?

    With more than 5200 miles in 304+ hours of use, and about 300 recharge cycles, My EG Zurich has performed flawlessly until lately. Now it seems to markedly lose power and sometimes shuts down when pedaling in headwinds and up mild grades. During higher power demand times the handlebar console...

    First Flat on my Fat Tire :( What is best?

    The best answer is to Slime your tubes before you get a puncture. http://www.slime.com/us/products/bike/sealants/tube-sealant.php With Slime in the tube, you will at least have the chance of not being flat while out on a ride. Carry an inflation kit with you...

    Optimizing Battery Usage

    Anecdotal experience has led me to these conclusions for prolonging Lithium-Ion Battery power: Never fully discharge the battery. Fully discharging the battery does not even seem possible with the type of controller on the EG Zurich. Allow the battery a period of time to "normalize" before and...

    Optimizing Battery Usage

    What gets confusing here Phil, is so much conflicting info. And there is no lack of specific conflicting ideas for maintaining and or revitalizing a battery. Paying close attention to the battery use this week I have become more aware that lith-ion batteries benefit from a rest period during...

    Very bad head shake or shimmy

    I'm guessing that a front hub motor may cause a more pronounced wobble than a rear hub. Whether front or rear drive, I would guess too, magnets in direct drive hubs may also be contributory factors for wobble on bikes with that type of motor. I would guess further, a typical crank drive set-up...

    Very bad head shake or shimmy

    I figure the wobble is caused mainly by the hub motor planetary gearing or perhaps from magnetic pulsation as the hub rotates with or without electrical input from the battery. If there was a practical way to compensate the imbalance then maybe the condition could be alleviated. Still, the...

    Very bad head shake or shimmy

    My EG Zurich suffers from the same issue. keeping one finger on the handlebar eliminates the wobble, so I've lived with the characteristic for the past 5,000 miles. Recently, I put the bike on a stand and while operating the motor on the stand I noted the wobble under no-load. It seems as if the...

    Optimizing Battery Usage

    After trying a more complete discharge of the battery and then recharging the battery -there may be a slight performance improvement. When the battery was new there was no appreciable loss of power on typical climbs during the first 30 minutes of use. Today, on a typical commute I continue to...

    Optimizing Battery Usage

    After speaking with Paul at e-bikes of New England, he contacted Wayne -owner of EG-Bikes. They have a replacement battery available which is comprised of Sony cells. Before I bite the bullet on the $510 purchase, I am trying a deeper discharge cycle on my present battery.

    Optimizing Battery Usage

    I have lithium-Ion cells in the 36V 12Ah battery pack, of which I am unsure of their brand. I believe they are supposed to have a usable life of 1000+/- recharge cycles. So after speaking with the owner of "ebikes of NE" and some blog info here and on "Bikejournal", I took a ride with a goal...

    Optimizing Battery Usage

    The 36v 12Ah battery for my EG Zurich is losing reserve capacity and maybe should be replaced. I have nearly 300 recharge cycles and 5100 miles tallied. The battery seems to be running out of power more quickly than when it was new. Making a call to (Link Removed - No Longer Exists) and...

    Battery Shipping

    Wow! This blog reads like there are some real issues with shipping Lithium batteries. The 36v 12Ah battery for my EG Zurich is losing reserve capacity and maybe should be replaced. I have nearly 300 recharge cycles and 5100 miles tallied. The battery seems to be running out of power more...

    Flat tires - how much of a problem should I expect?

    The controversy between "Stan's" and Slime continues? I have used both over the past several years. SLIME has proven it's superiority to me. Stan's has coagulated into a rubber mass inside my tubes during off-season storage. I get multi-year use with Slimed tubes, -it holds up without...

    Flat tires - how much of a problem should I expect?

    I have used "Slime" for several years now in the tubes of all bikes. Seriously good stuff! You don't need to pester a bike shop to install the stuff. You can purchase pre-Slimed tubes. Also consider buying Slime...
