    Why are cyclists so keen to race me?

    Because they have a need to prove something. Meanwhile, I am too busy getting to where I am going.

    An ebike for the hills?

    There is nothing that beats gearing to handle hills. What I am searching for is a much stronger chain (derailler use ---- with the intentional slack between links) but strong enough to handle the increased torque of a strong Cyclone motor. Not much luck sourcing this thus far. May have to go...

    Chinese Products: Buy at your own risk

    Unless you buy from a reputable and established importer who will stand behind their products, Chinese made stuff are getting to the point where they are more trouble than they are worth. Why should we invest real time (at US/Europe rates) to shop for, set up, and maintain their products ? It...

    Best riding tire

    The issue of "bounce" in bikes with either no suspension or average bicycle grade cheap suspension is major for performance. I have noticed that even a relatively inexpensive dual purpose motorcycle (with a decent suspension) outperforms a bike in its ability to keep tires in contact with...

    30 Million Tons of Lead Contaminated the U.S. from PR Stunt

    Peak Lithium: it's the new oil

    Nobody said "running out". The discussion is about "peak output". So please start a new thread on "running out" if you want. This thread is about "peak output". If you don't know the difference, kindly consult credible references or hire a qualified tutor.

    The petrol price in China

    Not so fast here! Gasoline in China tend to be slightly above the US Retail Average, though in practice, it is more expensive because it is a lower grade of fuel that contain high amounts of sulfur, but lesser amounts of diluents like ethanol or MMT. That is because gasoline is made from...

    Disc brake material

    A very simple way to prevent heat migration from the hub to the disk brake rotor is to insert a thin heat insulator between the two parts. A fiber washer would do fine. Slightly thicker than normal bicycle material for the rotor will soak up most of the heat, and very little will be...

    SLA batteries bloating up - damaged ?

    One possibility if your needs are not demanding is to buy cheapie Chinese SLAs that are a fraction of the price of CSB AGMs. I do that, and toss them out when I get tired of them... At $30 a pop... I can afford it.

    Ice creams pumped with air to cut costs

    You would be disappointed at how most stuff you buy are "cut".... and I am not just referring to plants or white powder. Pepper, for example, is rarely "pure" unless you bought pepper corns. Wine or beer are rarely "natural" but loaded with additives.

    Schwinn I Zip / Canadian Tire Bike / Rear Hub Bearing

    Update. Today, the front side pull caliper bushing (that presses against the return spring) broke on one side. This bike is really not built for serious use (defined as less than 10km per day).

    Electric cars attract hype, but reality is less exciting

    Nepal is the one place that seriously switched to electric vehicles in the midst of the 2007 and 2008 fuel crisis. I don't have recent news, but suspect that once the oil price bubble popped, everyone went back to gasoline and diesel.

    The REAL reason why biking on sidewalks is dangerous

    Toronto asked to keep e-bikes off sidewalks and bike lanes!

    You hit on a very good point. Right now, depending on jurisdiction, if you have a home owners or renters policy, there is normally a small amount of liability insurance that "comes with" and in theory should cover those claims. However, two things are likely to happen --- at this time, there...
