To be expected after 17 years…

Once every month, I check my TWIKE’s exterior for potential problems (like this one, or this one) that are easily fixed if detected early and turn can into very costly repairs, if left unattended. This entry shows you another part of your TWIKE you should check regularly – which I haven’t … until now. TW560’s […]

Post-TDE2017 TLC for TW560 (Part 2/3)

With part 1/3 TW560 taken care of, it’s time to put my focus on two other issues: After just one day of constant wiper usage during a storm in Hungary, TW560’s acrylic windscreen is badly scratched and needs urgent attention. When the sun or lights from oncoming traffic hits the windscreen, I’m almost blind. Lots […]

Post-TDE2017 TLC for TW560 (Part 1/3)

Unlike our many other yearly TWIKE adventures, TDE2017 took a heavy toll on TW560. Time to give TW560 some TLC and make TWIKEing great again! 🙂 First stop is at Andreas Martin’s Ksenotek, Switzerland’s newest TWIKE service partner in northern Switzerland. The 360° sphere below was created by me during TWIKE Klub Switzerland’s 2016 general […]

Hello 2017

Welcome 2017 – I haven’t been blogging for a while, there hasn’t been much to blog about anyway – having been rather busy with (international) travel and finally some well-deserved vacation, this entry is somewhat of a quick re-cap of the last few months. After my TWIKE-related accident it took surprisingly long to get rid […]

Update: Compact 3.7kW charger project

Picking up after where we left a week ago: After some debugging, I’ve been able to start communicating with the charger.   Assuming the hardware-related problems I had to solve before successfully receiving my first CAN packet are rare, I must say that the steps required to actually get packets from the bus and on […]

Solar TukTuk & TW560

For some time now, I’ve been following a very interesting project: Tejas, the Solar Tuk Tuk. Naveen Rabelli is driving his DYI-conversion of an Ape three-wheeler on a 10’000km trip from India to England. On his trip he is proving that very simple sustainable technology can be as reliable as mass-produced conventional technology and at […]

New Project: Compact 3.7kW charger & configuration

After installing TW560’s latest battery pack and testing it thoroughly, one of the points I definitely want to address is reducing full-charge time. With a potential maximum of 18.9kWh having to go into the batteries, my current setup with 6.8kWh peak charging capacity means I’m charging for at least 3 1/2 hours. Adding chargers is […]

My first 35E-week – a recap

New Battery Pack: How far can I go on a charge?

Every time when changing something related to batteries, many other parameters potentially change at the same time: Chemistry, response to load, max/min voltages and discharge curves, etc. In a way, it feels like being a novice TWIKE pilot again – you really don’t know how your battery will react and – in consequence – how […]

Finally: My 51Ah pack has arrived!

Samsung’s 35E cells weren’t available when I ordered TW560’s new Dreifels 51Ah battery pack. Thanks to a very kind offer by Ralph from dreifels, I was still able to go on my yearly TWIKE adventure and experience a large pack / range with his personal 29E/45Ah pack. During my vacation Dreifels sent me an email […]
