How's this for ultimate lounging - you could add a projector that projects onto the sail, not only could you read ebooks while you cycle, but also watch the occasional movie! very nice ergonomics, no need to strain your neck.

As said, the batteries need replacing. They have a limited lifetime, regardless of use. You don't say if they are lead acid or lithium - if lead acid, they will certainly stuffed. If Lithium they could last many more than 10 years, but only if stored correctly. If replacement batteries cannot be purchased the best option is probably a rebuild. Virtually all ...

I think it's obvious that you'll need a heads-up display in order to see the road through the text you're reading. Safety first and all that. So you're going to want to combine this project with a fairing. The alternative is to hack your reader of choice to use a scanning laser projector, in order to paint the text on the road in front of you.

This is an odd question. The sentiment that the only security here is physical security is correct. Think about the following: The Shimano Di2 components are not mated/matched to a specific computer or instance of E-Tube software. So there's no 1:1 relationship. Therefore, any computer equipped with the SM-PCE1 or SM-BCR2 programming cables can be used to ...

A serious answer - consider an MP3 player and an audio-book instead. While sound-isolating headphones are bad for awareness, a single (ie mono) speaker can work quite well. Personally I use two different items depending on the nature of the ride. A small MP3 player with a build-in speaker that lives inside my helmet buff. Its quiet and invisible and ...

What is the best E-reader to use on a touring bike? What will mount well on a drop bar, withstand the vibration, and not jiggle so much that you can't read it? Something like Google Glass (yes, The Glass is back) would be a good solution. There are several different versions of this type of technology. Products like: Optinvent ORA Vuzix M100 GlassUp ...

It should be. That's how I navigate on all my rides, wet or otherwise (phone on the bars). I've done this for a few years, but not completely without incident. Some tips: Make sure all port covers are tightly closed; I even grease mine very lightly. Consider how you will charge if necessary (I might otherwise plug in to a battery pack or my dynamo while ...

Right now I am at 159 hours of riding time on the battery which came with my GSC-10. Garmin's stated battery life for the GSC-10 is 1.4 years at one hour of riding per day which works out to 511 hours. (See page 51 of the Edge 500's Owner Manual) On the interweb I've come across two different suspected causes for low battery life on the GSC-10: Some (...

Based on comparison with the Giant Defy Advanced line, it seems to mean that you can run an electronic drivetrain (such as Shimano Di2 parts) - you have to mount things like a battery in order for the shifters to work and what not, so the frame will need to have the wiring harnesses and battery pack mounted. This link shows the TCR line in 2012 with this ...

Perhaps instead of password protecting it, you might want to think of ways you could detect that the device was tampered with. I'm not certain how often you would change settings or plug into it, but you may want to cover the port with security tape or something similar so that you are aware when somebody has been messing with the equipment. This may not be ...

Rohloff has developed electronic shifting for their hub; Shimano offers an electronic-shifting add-on for Alfine. I'm not aware of any such from SRAM or Sturmey-Archer.

According to BikeRadar, "The battery unit as well as the wiring for XTR Di2 are identical components to the ones used in Shimano's electronic road groups. The battery can be mounted on a bottle cage, in a seat tube, frame and can even be contained within the steerer unit of certain forks (via the use of PRO's new Tharsis components)."

You can reset the Wireless passkey - even if you don't know the current one - by connecting your bike to a windows computer/laptop using the charger.

Speaking in terms of past few decades to current generator hubs and lights, mostly they are interchangeable, with some qualifiers and exceptions. Almost all current hubs and lights are based around 6 volt, 3 watt, and can all work together. Usually the deal is your hub is going to have its own connector type which it will probably come with, like the two-...

You’ll be fine assuming you have a recent phone. They’re entirely glued and sealed shut on the inside, and there’s no battery hatch or anything to worry about either. I ride with my iPhone 7 (only IP67!) in the rain, which I’ve had for 4 years now with no issues. Heck, I wash the thing in the sink and it’s still going strong. If you’ve ever had a battery ...

There are two parts to this question A 10 year old bike that has been out of use for a while Check tyres for cracking and flaking. Inflate, and if the tubes don't hold air then replace them (patching tends to be ineffective when the whole tube is old.) Brake pads also go hard with age - if the brakes are poor then replace them. Rust - chains and cables ...

Barometric pressure is not the only feasible method to track altitude, but is by far the more practical in terms of power requirements (I have a watch that lasts 2 years on a battery with altitude), size and cost. GPS Altitude is wildly inaccurate due to the geometry of the satellites. Unfortunately to cope with very small signal errors you need a ...

The simplest on-the-road solution is to get a detailed paper (walker's?) map with contour lines. In the UK, Ordnance Survey provide these, for the USA you could try Omnimap. Alternatively, there are plenty of online tools, like freemaptools.com which use Google Maps. You click on a point and it gives you the elevation.

Yes in theory but the gain is not practical. You’re better off swapping batteries than trying to jury rig something. Let’s do the calculations. You note that the AC charger puts out 36VDC at 2 amps. That’s 72 watts per hour. Even a modest eBike has an 8Ah battery, for a total of 36x8 or 288 watt-hours. At 72 watt-hours per hour charging it takes four ...

Here is a video I found which is very detailed and shows how to add a second battery to your bike: Video: How To Add 2nd Battery to the Fiido D2 Here's the link to the battery which was recommended a ways down in the comments section: 36V 10Ah Battery Supplier In the video he explains that you are adding the second battery in parallel. Thus both ...

Yes, of course, that's possible. You just plug the cables into the brifters. Peel the grip-covers forward and you'll see unused ports underneath. Those may be used for sprinter buttons or for climber buttons as well. But I'd suggest you replace a triple box by a quintuple box (Shimano SM-EW90-B 5 Port Di2 Junction A) to make the connection easier without ...

If the AC/DC convert is a simple rectifying bridge plus filter and voltage stabilizer, it should work with a direct current source as well. The only question is how many batteries connected serially you will need to reach the minimum acceptable voltage. Given that specifications for your lamp say to use 6 V A/C you can go with four AA batteries or two 18650 ...

adding to Chris H 2018-04-30 post... I'm going to take a stab at some basic math... BLDC motors can put out their rated power at high RPM partly due to air cooling enhanced by the high RPM (like computer chips, if you add active cooling, they can go even faster... it's all about how much heat they can dissipate). At lower RPM the motor gets less air ...

Answering the other part of your question - Yes you could take the electric bits off and use it as a normal bike. You'll want to take some links out of the chain to account for the skipped/missing motor drive cog. Depending on the rear dropouts you may be able to tension the chain using the parts of the motor drive, or if they come completely off then by ...

First up - I know nothing about your specific bike model. However 3 years is a pretty good run for batteries especially if used for hill climbing, and it could be they're just past it and need replacing. 600 euros sounds a lot, but its one of the consumables. Do you know how far you're ridden? 10,000 km would be 0.06 euros per km, which is a lot ...

When you remove the Nyon from your bike, don't turn it off, as removing it from the bike is its signal to transfer data by bluetooth to your phone. It then turns itself off automatically after 5 mins.

I have two Nyon computers and I can assure you they both connect to WPA and WPA2 secured networks. BUT this doesn't work reliably! Sometimes it works, sometimes it doesn't. Often it takes a dozen attempts (and password re-entries) or more (!) to finally establish a connection. Have you tried to disable bluetooth on the unit? As bluetooth is using a similar ...

I was able to connect to an unsecured WLAN with my Nyon. I updated the Nyon and tried to connect to a secured network again, but no luck! I'll try to contact Bosch support about that problem too. I see following possible workaround's in the mean time: If you only need to sync your cycling data, you can use the mobile app and connect via Bluetooth. If ...

If you have a bike with Shimano Di2, physical security should be paramount - I'm not sure why an unsavory person should even be physically near enough to the bike to be able to make those changes. And they'd have to be carrying the right cable and everything. It seems like a highly implausible situation to occur, and certainly which should not occur ...

White stripe is ground. Consistency is a virtue, and Schmidt's obvious decision tells us the industry default. In principle, the two conductors are interchangeable, because AC. However, in the reality of bicycles, there are practical considerations. Some dynamos ground one side of the circuit through the axle and some don't. Some lights ground one side ...
