Hi there, One Too Many is a fusion of some of the games I like to play. My aim was to create a collectable card game for the wide audience. This beta preview includes the full game functionality, but no art work. It is also not optimized fo

It's been a while since I last stumbled upon such a novel idea. With Robinhood and company getting into the betting markets, I'm afraid this idea will get a bad image and make it's adoption harder.

To me, NY Times' article lacks empathy. Andy Baio's farewell blog post is much more reflective of her personality and life, and so is her 2015 XOXO talk. https://waxy.org/2023/05/goodbye-dooce/

Thank you! A better (more solid) connection between the kit and the frame would be on the top of my priority list, if I were to build it again.

Thanks!

The decision to select this motor was mainly driven by what is available, price, dimensions and the size of the output shaft. The gearbox would not fit anything that has an output shaft smaller than 6mm. I knew that I'm not going to ne

The basic idea for the freewheeling chainring comes from tandem bikes, where one person should be able to pedal, while the second one doesn't do anything. I have never ridden a tandem bike, but this is where I got the idea. There is al

I used 4mm thick, black anodized aluminum plates. I'm not a machinist and do not know the specifics of your CNC machine, but you will most probably have no problems machining these plates.

Thank you! Yes, brakes are important and I have 203mm discs front and rear. After building this, I'm dreaming of building something very elegant - a 50W to 100W torque generator that is tiny in size and very lightweight, and it fits wi

This is a good point, thank you! I take this very seriously and I'm very mindful when riding the bike.

Thank you! I'm mostly going to ride it on flat off-road terrain. I'm not really happy how those XT connectors stick out :/.

Yes, I have a long commute to work (18km one way) and this was my main motivation for building the bike. On the controls side of thing, I have the ECU and an Arduino Nano. The Arduino uses the BEC port of the ECU as a voltage supply to run

I designed it for 40km/h max, but this is way too fast. Given the KV rating of the motor and your max voltage you can calculate the max rotational speed of the motor = KV*V. From there it is just a matter of multiplying by all gear rat

The cost that I mention in my post doesn't include the cost of the bike. I payed 1212€ just for the kit.

The torque is not adjusted I any way. I really designed it in a very simple way - you turn the throttle and adjust until you get the assistance you desire. The human brain is an excellent controller and after a while you stop thinking about

I got the gearbox used on eBay for about 100€. There are plenty of them available.

On a full suspension bike like this, the distance between the rear wheel and bottom bracket changes when the suspension works, so you need a way to compensate for this.

Thank you, those are great suggestions. The ECU selection was primarily budget driven. I need to have a look at those VESC. Battery selection was again budget driven. The also hat to have certain dimensions to fit inside the kit.

Yes, this is how it works on thin cables, but the ones on the ECU are very thick and very hard to tin with soldering iron. I finally managed it, but it was a fight. I’m using the TS100 pen.

You are right. It is meant to be driven on unpaved flat off-road terrain. Mud and water could be problematic.

It’s just a zip tie. It only needs to support part of the weight, the moment from the kit is reacted by the frame itself, e.g. the motor pushes the kit against the frame, when it drives the chain.

I live in Germany myself. I mostly built this bike for fun.

It is very hard to tin the cable ends well and tinning is key to soldering. I have a proper soldering iron, but no special device to only tin cables (I’m blanking on the right word).

I have no manufacturing capabilities at home. All custom parts where procured by external workshops. I designed it, so that I can order parts and put everything together at home.

Just conversion. The frame made by Nicolai [1] and I bought it used on eBay. [1] https://www.nicolai-bicycles.com/

I used PETG. I’m happy that I tried it, but it is hard to make 3d parts work, when they are subject to loads.

It’s not waterproof. I got the sheet metal parts from Schaeffer AG [1]. Thanks! 3d printing is here to stay, but load bearing parts are problematic. I had to change some of them to metal. [1] https://www.schaeffer-ag.de/

Yes, this is exactly how they are manufactured. I got them from Schaeffer AG [1] and the three plates cost approximately 300€. [1] https://www.schaeffer-ag.de/
