EddieJ, a German version of Court who does this sites reviews.

3 speed internally geared hub combined with a 9 geared cassette is so smart. I can't believe this hasn't been done before. Probably the future of how bikes will attain great range.

Guys you put a whole new light on pedal assist. I didn't realize the work required varied so much. I guess the idea behind pedal assist is, you have to be alert if you're moving you're legs.

J.R. that is one of the funniest videos I have ever seen. Population down in Sheffield due to 3 wheel deaths.

KenM, thanks for the posts, they are like a long term update on the Motor Week TV show. Many bikes have gone to 48 volt. And in the same price category as http://store.genze.com is Radpower bikes. They use 750 watt motors. When I see riders on YouTube with lower watt systems, they really...

Bike helmets help when you are on foot and take a slide on a mountain. Lots of surprise jagged rocks.

Court interviewed the electrical engineer that runs GRIN technologies in Canada. The engineer was testing to weed out old wives tales, and see what really goes on. Good batteries like Samsung have protection circuits that prevent overlow discharge damages. But the biggest factor in battery life...

It has been my experience that GPS systems can give less reliable readouts. Especially around tall building or enclosed hills. I had a Garmin jog tracker wrist gps (returned it), it showed me hoping from 1 side of the street to the other and even more crazy stuff, on a straight run, when...

This happened to me. The cause on my newer bike was a buildup of chain lube on the geared cassette. Orange clean and an old toothbrush fixed the problem.

1 incident would have to be applied to a broad type of circumstances. Many Ebike companies are small, that can't be to blame by it's self. But all Ebikes could be required to have 200 mm hydraulic disk brakes with standardized motor cut offs. No brand should be blamed from what we know. But the...

Sorry @I bought A2B, I had a wreck also and broke my fibula. Pedaling a bike caused rotational stress and I couldn't do it. This bone usually has low pressure joining it so a pin is needed. I skipped that and could walk or jog for 4 years until enough calcium had formed to stop it from popping...

Thanks Ann for pointing out this maker. I would imagine their bikes are more reliable than others due to their repair expertise. Prices are low also.

The display listed 40 kmh but the announcer said 0 to 20 mph. Higher numbers might not actually be settable.

technomadia chris, An example is Giant bikes. They don't give weights, only a message that it depends on stuff. I think the idea for keeping these pieces of information secret is that competitors will lie about weight or size. And keeping the data private stops a lied about stat from being...

The sharerooler seems like it would wear the tire like a training roller does. Being made out of polyurethane helps but I would have to see it to believe their statement that it does not wear the tire.

Freakyguy666 any chance that was a shipping injury? Or did it seem a manufacturing problem?

Volkswagen syndrome might be happening, false stats being advertised. I am just guessing but from the E.U. laws I would say the light Haibike could even be maxed at 350 or 250 watts.

Efficiency is something that needs a scientist to measure, but cross gearing, setting the chain to a diagonal hold, seems to create the most binding for me. Another source of great inefficiency is cheap sprocket cassettes that have a 32 or 34 tooth that bends when slightly cross geared. I had a...

Thanks for the info guys. The solder might have mercury is a worry. I noticed the RadRover has 12 gauge spokes(or 11 gauge, a lot of websites for Ebikes have small typos for some reason). I am sure if I could get to scooter or motorcycle thickness, goodbye spoke trouble. Amazon has bad reviews...
