This site is closing

This site will close soon, probably at the end of this months billing cycle, in around 3 weeks.

The reasons:

  1. Constant hacking attempts, as many as 200 per day. They’re coming from all over the world, so a script kiddie trying to get access by using incorrect usernames. I have a firewall in place that bans them after one failed attempt, this is fast becoming a very large part of the database and .htaccess file.
  2. The site at certain times of the day can take an age to load. This is unnaceptable and throwing money at the problem won’t help.
  3. I’ve contacted several retailers and manufacturers to see if they’ll loan me a bike for a few days so I can expand the reviews to cover other models… none have called me or emailed me back.
  4. I can’t be arsed updating with new posts. There’s also little to cover if I can’t get hold of loan bikes to test and review.
  5. I might one day setup the site on my local network on a raspberry pi, and yes believe it or not, it would be faster than the current host.
  6. I’m also considering selling my bike. I am a carer for my uncle who is mentally handicapped, I get 3 days a week when I have a respite carer come in and look after him for a few hours. So of course riding is dependent on the weather and if I have other errands to run in my spare time. As things are. I don’t want to get soaked, cold and miserable during this time.

At LAST! A Spare Battery, and my old one is a donor for experimenting.

In my last post I considered a new battery because mine is getting a little weak, and this week I ordered a new battery and have just had it delivered.

With the battery came a leaflet from the manufacturer, Phylion in China. Jinshajiang Road, New District, Suzhou, P.R. China. Postcode 215153

Tel +86-512-6832-0283

Model Number: JCEB360-11

36v 11.6AH

So that’s the company and battery details, my question is… are you someone who knows about electronics and BMS, do you know how to read and reprogramme said systems?
Can it go faster than 16mph? Can the cells be replaced with bigger amp hour cells?  Can a barrel connector be made to charge the battery on the fly (while cycling)?

Ebike Range Anxiety

My bike and battery are now well over 2 years old, and my battery is begining to lose its capacity. I didn’t follow my own instructions on battery care and left it charged to 100% for a few months, and on more than one occasion. Plus when I did my 45 mile ride I dropped the charge all the way down to 2%… VERY NAUGHTY I know.

So as a result I’m now developing range anxiety, and instead of riding 25-30 miles in one go, I’m dropping this to 15 miles. So I’m worried and I need a new battery, but Halfords are currently out of stock of spare batteries. Then I started wondering if it’s possible to charge the battery with a power bank phone charger.
I’ve fired off an email to SR-Suntour to see if they can help, this is the email.

Hello to who ever reads this email.

Just over 2 years ago I bought the Carrera Crossfire-E from Halfords, and it’s been a blast riding this bike, your battery and motor make this bike awesome. I even made a website to share my thoughts and opinions https://the-bionic-cyclist.co.uk

Lately I’ve had a reduction in battery life, probably because I left it fully charged for too long, but hey this is England and the weather is totally unpredictable. The reduction is only around 10%, so even though I’ve not charged it the stated 500 times, I understand how Li-Ion batteries work and their limitations.

This brings me onto a couple of ways you the manufacturer could fix this in future.

1. Have the USB output stay on even when the LCD is off, this way I could easily discharge the battery and keep it around the 30%-40% mark for long term storage. Dendrites are the enemy after all.

2. The ability to charge the battery on the go, without mains power…. Wait whut? Yes, there’s now a metric tonne of power banks, some with 3, 4, 5, or even upto 20 18650 batteries installed. Sure they’re a little heavy, but so is a spare battery. So why not add another USB port that allows a rider to charge the battery while on the road. I realise there are limitations on powerbanks, mainly that they run only at 5v and a maximum of 5 amps. But a trickle charge still adds a few miles to a ride. Or you could manufacture a powerbank that outputs 36v and a socket to the main battery and charge a little faster.

The benefit of number 2 is simple, you could sell your own rechargeable power bank just for your battery packs (watch out for the input socket, it could get damaged, you could then have the spare power bank charged by another power bank… and so on,) and they would work with all your batteries out there now. It’s lighter than a spare battery and it should be a lot cheaper too. An extra 5-10 miles is still miles ahead of the competition.

The alternative is to add a USB INPUT to future products, but this leaves all current and future batteries limited to their initial state.

Personally I prefer number option 2, it’s flexible and adds a little more distance to all past present and future batteries.

Now on to a couple of questions I’d like an answer to please.

1. Where do I buy a new battery from? Halfords haven’t had the stock in a long time and mine is now giving me a huge amount of range anxiety.

2. Do you have a publicly available schematic for the battery? If I bought a new one then I’d like to teardown the old one and replace the 18650’s with improved new ones… thus giving me 2 batteries and preserving the old one to make it last another 2 years or more.

Please let me know what you think, personally I like the idea of charging on the fly, and I’m amazed that no one has yet thought of it. But if I’m wrong and it cannot be done or it would be impractical then just a quick reply will do.

 

What do you think, do the ideas have merit?

 

Cycling videos with Data!

I recently bought a Garmin Virb and shorlty after I bought a GoPro hero 6, these let me show speed, inclination and distance data amongst other things. I found the video to be far too compressed with the Garmin, though it does store a huge amount of data, the video from the Gopro is far better but it contains less data. But all the important stuff is there.

 

 

  •  This is the GoPro at 1440P, though it can do 4K 60, but even my monster PC struggles at that high a resolution, 4K 30 is excellent, but I find 2.7P 60 to be really nice and hardly a downgrade on clarity.

  • This is the Garmin Virb, the video is nowhere near as crisp and clear, but man it’s easy to use and has incredibly well rounded software.

  • And this one again from a GoPro hero 6

Carrera Crossfire-E Electric bike – Power Cut

Now fixed: https://the-bionic-cyclist.co.uk/2017/10/15/the-dreaded-power-cut-fixed/

It seems that despite Halfords and SRSuntour’s best efforts owners are still suffering power cuts from this otherwise excellent bike. I have a fix for this, sadly it’s not permanent but it will reduce the cut out to a minor inconvenience.

On the rear of the bike (left hand side, by the rear wheel) there is a neoprene patch held in place with velcro, remove this patch to show a large barrel connector, this is the power supply to the motor on the rear wheel, disconnect and reconnect the barrel and reattach the neoprene. All done it takes less than a minute.

That’s it, it really is that simple, I do this and I’m good for another 50-75 miles before I get another power cut. Or you could do this before you set off and hopefully prevent a power cut.

Let me know if this works for you or if it’s still frustrating you, or if you’ve cured the problem completely let us all know how you did it.
