Re: E-S Stealth Electric Bike Owners

Finally, my custom Bomber build has gotten a TÜV approval and is now a street legal e-motorbike. :-) It´s fully equipped with Heidenau 18 inch * 3,00 motorcycle tires, LED head, tail and brake lights. An electric horn is also aboard. A rear kickstand had to be made for this build and is self retract...

Re: Street LEGAL Custom Bomber build! :-)

That's the most important issue!

Finding a TÜV engineer that instantly falls in love with the bike.
Those that have a heart and consciousness for all the work done,
are exactly what you need.

The rest is a lot of paperwork and nothing compared to
building the bike. :-)

Re: Street LEGAL Custom Bomber build! :-)

That's true, most Germans are paralysed by fright. It's called the German Angst. So they sit around watching garbage on TV, repeating the junk others tell them and never have a really personal opinion about whatever. But there are exeptions. The stated scenario is a worst case of course. :-) But tha...

Re: Street LEGAL Custom Bomber build! :-)

That sounds like a good idea. As long as you take it easy with that extra power. Doing 70 km/h on a bike lane will surely catch someones attention sooner or later. But there´s always the forests here. Just a few days ago a feral pig almost ran over me while riding around the forest. Animals don´t ru...

Re: Street LEGAL Custom Bomber build! :-)

In Germany every builder faces the same problem. That´s why the guys in the Pedelecforum are so afraid to go for more power. On the day of registration a cop passed by and we talked about the legal issues. He told me the following: If they stop a rider with a vehicle that has more then 250 watts and...

I 14. Speed limit of 45 Km/h. Has to be tamper proof! I'm curious, what did you need to do to demonstrate that the speed limit was tamper proof? That wasn´t too difficult. Programming a speed and amp limit did the trick. They made a test ride afterwards. Being honest the possibility to add a 3 way ...

Thanks guys for all the positive feedback. :mrgreen: The best part is that riding around now does not put me in jail if the cops ever happen to pull me over. The second best part, even though they will never find out about this build, are the Pedelecforum gurus that still believe 250 watts is what e...

Chain guard around the radius where the cranks rotate. 2. Detailed information about the battery. ( Cell type, manufact...

Ok guys ( and maybe girls too ), it´s time for a status update. Today is a wonderful day! The TÜV has approved the bike as street legal. All the necessary documents have been handed over to me.

Well it´s a bit early to pour champagne into the glasses and celebrate, but at least they haven´t refused the whole project in General. I have a lot of writing to do now. Also a photo album of the build is needed to apply for a serial number. Just finished uploading loads of pics in order to get rea...

Here we go guys. After 2 years and 8 month my build is undergoing rigorous testing here: http://i62.tinypic.com/2qv8htc.jpg So much work was done prior to my visit there for getting it street legal.

Re: #1 The long road

Yup, my frame weighs 10,7 Kg including the Vboxx and swingarm. A friend of mine works as an engineer and calculated the frames rigidity. He told me that there´s about 2,6 Kg of steel that could have been saved. But this makes for a super tough structure. At least it feels very sturdy. Nothing feels ...

Splendid. This makes me think about updating my TIG welding system in order to be able to weld aluminum.

Looks so neat and professionally done. Not just like a purpose build. :mrgreen:

Re: Cube ( Custom Bomber ) build. FINISHED !!

A heavy bike needs a good kickstand :) good idea to consider about motorcyle stands.. Do you have access to water jet cutting or are the steel sheets hand made? nice work! The steel sheets are all handmade. There's a company just a few Km from my place that laser cuts steel sheets. Since they need ...

Re: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tir

Here´s my spoke source for anyone in Europe looking for the high quality stainless steel type.

They sell them in different sizes too.
Ordered 2 sets for the front and rear wheel and got them in about 2 weeks.

Re: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tir

Does anyone here have a good source for motorcycle fenders?

I´m looking for an 18 inch version that will cover a 3 inches wide street tire. :-)

Mounting brackets and clamps for the front fork would also be very helpful.

Thanks…….

The self retracting side kickstand arrived today. A new mounting plate to fix it to the swingarm will be fabricated tomorrow. That will conclude all the TÜV demands.

Yes, the motor will definitely take this current. I´m a tall and heavy guy with 1,98m * 94 Kg. That puts a lot of strain on the motor.

Re: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tir

Thanks to the heavy battery of around 16 Kg and the motorcycle rims plus tires the front stays down. The X5404 does make me curious. It should give me better acceleration. I could live with a lower top speed. :-) This weekend I'm working outside my he so the photo update will have to wait. A good fr...
