There is a chain tensionner for mounting Rohloff hubs in vertical dropouts. It replaces the derailleur and also helps improve the chainline. http://www.rohloff.de/en/technology/workshop/dropout_styles/

Thule is Swedish, almost as good as German engineering ;) cwah did you see the structure under the seat example? The weight is held by the single vertical tube, the others are there to brace that tube. You have nailed the basic problem: racks for carrying heavy loads do not work well on full...

Of course they make folding cargo bikes in the USA! https://www.bikefriday.com/bicycles/haul-a-day_basics they even have a Bionix version!

My "design" requires flat aluminium bar AND tube. And NO it won't work if you extend by 50% as you have drawn. Yes I think your best choice is the rack above. I hope they supply very strong frame screws... A folding trailor fits in a tiny appartment, I live in one. Think about doing more...

I did a quick and nasty paint drawing on your photo. The weight is supported by the vertical tube. Even your soft aluminium tube is very strong if it takes the strain lengthwise. If you use flat aluminium bar for the bottom "V" it will be stronger than flattened tube where the short...

If I buy a battery it will be coming from China. I won't sell before receiving another battery, remember this is my "car", not my "toy"...

I think that they might have a use as a serious working tool on the farm in NZ. They are of no use here in the Basque country unless you want to ride in the snow in the Baztan valley for example. Maybe in the Landes and up into Vendée for riding on the long sandy beaches? Onroad useless IMHO and...

OK some math: You have a 25kg box on your rack which is attached to the non suspended part of your bike. You hit a pothole and the wheel is accelerated to 3gs (not unrealistic) you box breifly weighs 75kg. In fact because of the angle of your tube you are subjecting it to even greater forces...

Your tube is strong enough, your design is wrong. In design school we had one interesting challenge: build a bridge from the least amount of 1/16" square balsa with a 30 cm span between two bricks that would support another brick. With the right engineering you could make a bike rack from any...

My dream bike is a HPvelotechnik 26" Gekko with either a pinion box on front and a rear hub motor or a bafang 250W motor up front and a Rohloff in rear. For using as a human powered trike I would just take the battery off and ride as is with the extra 3-4 kg weight on the trike. The motor will...

I am already at the stage of needing a second battery. My initial plan of needing 60km range kind of flew out the window as I got the pedelec disease and always having " just a few more km then home" fever... Plan A: buy a new bottle battery case with controller to put current cells in and a...

I'm a rower, padded underwear is for sissies... :p Seriously, I have a friend who puts foam on his skiff seats and rowing his boats puts my bum to sleep. The saddle I showed above has some padding but on a bike you are changing position much more than in a skiff. I like the sensation of gel...

Ah Perth! What a happy memory! And I have a dear friend in Dundee, he is Greek, go figure... Back to bikes, can't you pay the £45 extra for the bike you like from your pocket? I mean I am a card holding member of "the working poor" and broke my piggy bank to have a means of transportation for...

Today I passed the one thousand kilometer mark. The ride was especially chosen for this milestone with lots (LOTS!) of hills and some fabulous scenery. As an apetiser I rode the usual 11 k to the station. First course: from Zumaia to Deba is basically a climb to 260 metres that is about 10...

This looks like GEN 2 of BBS02 motor. I really like the new triangular bottle battery shape they show in the kits page.

I also have a triangular frame bag (for the moment) and just cut a hole in the bottom corner for cable entry. Much tidier than the under seat bag that came with the kit. Next version will be an inside the bottle battery controller.

Under 20€ from bike-discount.de Velo bio:logic. Longest ride: 80 km without pain! :D narrower than the photo and "dynamic" riding style. Next time I will break the piggy bank and go for one with gel, the SELLE ITALIA MAN Gel Flow looks good and is 60€

Ah-ha! I "dropped" the MacOs for Linux for the very same reason in 1997. I did have a Mac in the house again since OSX beta came out.

Summer sale in July in Spain, last version of old stock with the front motor. At 699€ it is good value, at 999€ not so good. I had actually gone to buy him a Rockrider 3.40 to act as a host for a kit. They were on sale at 149€ (the ones in unpopular colours).

Today I had the chance of putting in a few km on my mates bike. He bought it on sale at 30% off retail because, I think, it is a first generation model with a front wheel hub motor. It has a Bafang motor and a 24V battery. I told him the battery was not an issue as he can upgrade to 36V when and...
