On the rack if I use one battery or maybe moving the two batteries on the sides of the frame near the rear axle, one on each side of the bike.

Managed to make room for full size fenders and found a good place for the ring lock (in the back under the tail light)because I can see how this stuff would make my life easier, thanks for pointing them out! Also I will try a Nexus 7 speed hub and a 7 speed Shimano Tourney on the bike since I...

Hi guys, it took me a few days to integrate many of your suggestions in my design but I am very happy I managed to do it. First the geometry: I wanted to be able to build the bike with parts I already have, because I have many different parts from past projects. So with this geometry frame I...

48v 18 ah battery, sorry, my bad.

Yes, the 3M reflective tape is very good! The bike will also have front and rear lights. Maybe led strips on the side, but would love to insert them in the frame somehow, with small round holes in the steel tubes... I mean I would love the look, not sure about the strength of the frame being...

And with this frame shape I have room for two 17.4wh 48v batteries. I think this should give me enough range and does not take more time to charge. For now I only have one battery and probably will try working only with it, but its nice to know I have room for another one in the frame.

Thanks for clearing this up for me! Maybe I will try the Schwalbe Big Ben 26x2.35 for the courier bike, they certainly look more comfortable than some skinny road tires .

I made some sketches for a bike with 26" wheels and 100mm front suspension. Rear suspension would complicate the project a bit more than I can handle right now... This way I can use parts from other bikes I don't use anymore (I have old 26" wheels, hydraulic disc brakes and a rockshox argyle)...

The ring lock is a good idea, thanks! I understand your point with the cargo box position. With what kind of weights becomes this a problem? I had a mtb with a rear rack seat for my son that was in a similar position and it was ok.

The elevator is 1.5/1m with a 2m height... So the only way to use it is to get the bike vertically on the rear wheel...

Thanks for your comment! Do you think a suspension saddle post would help improve your comfort? There are some pretty cheap ones that would maybe help? How big is your battery pack? And what range does it give you? If you can give me more info on your real life range vs how much do you have...

I tried to understand your comments and I am sure it helped me gain a better perspective on what I want to build. The Arrow 7 ebike was very interesting to read about and also gave me a good ideea in what working as a courier may be like. So by now my project has evolved into this: Moved...

Nice one! Thanks for giving me a more accurate perspective on the aero energy efficiency. The site is awesome and I will also use it in future projects. Thanks

Probably I will try some S355 steel, worked fine for the boardtracker and I know were to buy from. Chromoly would be awesome but its pretty hard to get it here and very few sizes available.

Found this in the Arrow 7 topic: I love almost everything about these bikes... - Comes stock with crazy powerfull hydrolic mineral oil piston-caliper disk brakes. - The frame is a tank. I feel it was designed for delivery guy who spend their days rolling in New York Manhattan's pothole-full...
