Having fitted lights powered off the main battery that complied with German standards I was astonished to see the clear horizontal beam cut off. https://www.pedelecs.co.uk/forum/threads/stvzo-lights-with-lenses.35542/ It got me thinking about the backup battery lights I was using on country...

I did a previous post, thinking that I could find a helmet with a good sun visor. https://www.pedelecs.co.uk/forum/threads/cycling-helmet-with-sun-visor.34981/#post-508080 having checked them out, they did not offer any advantages over my existing helmet. Now that the low sun is back I thought...

https://www.pedelecs.co.uk/forum/threads/power-cutting-out-on-bbshd.35681/ My previous thread was trying to find the fault - & suggestions lead me to firstly check the battery.

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0222905 Long but interesting article, examples used were motorbikes but the principle remains the same. The conclusion is that a significant proportion of drivers simply forgot seeing the bike, so drive defensively.

today the power cut out on mile 10 of 15. On return journey sometimes it only lasted seconds. Suggestions please to allow me to identify the problem. On the way back I identified the problem could be 1- Battery (cells or BMS) 2-wiring from battery to controller 3-Controller 4-wiring from...

This morning going along the single track country road, numerous bends, short visibility. Normally I hear a car before seeing it come around the bend, but today for the first time I met an electric car. As its a single track road, I did what I always do whether riding or driving and stopped. The...

Help please. I have been looking to buy a cycle helmet with a sun visor, but whenever I search using that form of words all I find are normal helmets with a tiny visor, that my existing helmet already has. This morning across the traffic filled main road I spotted another cyclist with a helmet...

Anyone know the real story? https://www.dailymail.co.uk/news/article-7137183/2-5-mile-cycle-highway-caused-traffic-chaos-barely-used.html As on the face of it, gold standard infrastructure, a separated bike lane

I was going to post to ask with help in balancing the battery, but today it fully charged for the first time since February. Battery was described as 52v 17.5ah Lithium battery pack using Panasonic or Sanyo NCR18650GA cells sticker on battery says 2017, but I purchased in January 2018 I...

I can remember the fuel supply & price hikes in the 1970's, which lead to changes in driving styles to increase economy. When cycling I am often overtaken, only for the car to then brake to make a turn, when a few seconds delay behind would have achieved the same time at the turn without...

“Our results demonstrate that a single stripe of white paint does not provide a safe space for people who ride bikes,” Dr Beck said. “When the cyclist and driver share a lane, the driver is required to perform an overtaking manoeuvre. This is in contrast to roads with a marked bicycle lane...

I saw this & thought it might interest others. If anyone can translate from Dutch that might help! The graphic above is by SWOV, the Dutch institute for road safety research and details the relative risk posed by a variety of modes of travel; from walking up to HGVs.

https://www.sciencedaily.com/releases/2019/02/190212120114.htm Pedalling at cadence greater than 90 revolutions per minute is advantageous for professional cyclists, but appears inefficient for recreational cyclists. When cycling at low exercise intensity, skeletal muscle oxygenation is mostly...

Having read various articles saying that the law was going to be changed, I contacted the Government to find out how it would be enforced, after a van brushed my shoulder as it overtook me. Here is the reply I received today. "Thank you for your email of 7 January to the Department for...

This was taken at 50m, showing wilkinsons high intensity led at top, with a normal bike led underneath and my experimental LED strip lights. When I have followed other cycles I thought that its the size not brightness that draws the eye. So using 5V flashing LEDs I mounted them onto my rear...

I know the voltage before & after ride & mileage is this sufficient information? I have a 52v 17.5Ah battery. 100% = 58.8v 0% = 42v so 16.8v range. if I start at 55.5v (55.5v-42v/16.8v = 80%) & use say 15% of the battery to cover 15 miles I can compare different assist levels But without...

Having owned & used a 250w ebike for 5 years I have spent a lot of time thinking about my safety when cycling. If the government could be persuaded to raise the speed limit this would increase the safety and could Halve rush hour traffic congestion Halve the air pollution from peak time traffic...
