I forgot: don’t buy Amazon. After we know exactly what you decide to build, we will suggest the best places to buy and what you need to order.

Re: Best Ebike for a Newb with Motocross and DH MTB Experience?!

It is about how you want to ride. A BB drive will retain the bike feel, with its ability to jump and ride technical trails, achieving close to the same downhill speed that you are doing now. A hub motor build can be much faster, and you can build single speed. It will be handling in between bicycle ...

I'he put parts on scale before typing them here.
Weight the bike, not the math. True weight can’t be found adding the weight of components. It just never happen to be exact. The error adds with each measure, and we always forget something.

Re: Sortimo electric cargo trikes

Maybe the misunderstanding is coming from Papa’s perception of ‘fast’ If you find that 25 Mph is fast then yes, some cargo trikes are safe to ride fast. That is if you are keeping from cornering aggressively. On a leaning trike, I would feel confident riding 60 Mph and overtaking a car inside a turn...

Re: Upgrading discs to 203 mm - worth it?

Well, larger rotors, floating or solid, are meant to be used with larger calipers that have twice the pad surface. The Hope 225 mm that I use, were made for their M6 caliper that is huge. All together, a properly matched and set bigger brake combination, is making a better brake. And yes of course, ...

Re: Sortimo electric cargo trikes

That is the purpose exactly: A trike that does handle speed and power safely. Because that is the most important turn off to trikes, to have horrible handling at speed. Help me out here... I'm a bit foggy about your statement. Are you implying that non-tilting, utility trikes are slow and unsafe? T...

Re: Sortimo electric cargo trikes

Tilting designs offer NO advantages at lower speeds - and if hauling cargo, reduced payload capacity. And hauling on slick streets??.. Forget it. You can build significantly cheaper and carry far more payload with a non-tilting, 3-wheeled delta platform. That is the purpose exactly: A trike that do...

Re: Upgrading discs to 203 mm - worth it?

Floating rotors are pretty common, although not so many manufacturers are making them. The best that I have found are Hope, and one that doesn’t exist anymore because it didn’t sell enough, the Magura Venti that I still use on my dirt bike. A new manufacturer offering some is welcomed, for it might ...

Way back, before planes and bikes. Riding and flying are the same in ancient languages, and it was a tradition to give bird names to the best horses.

Re: Sortimo electric cargo trikes

Good design that could be built with lots of power.

For the price they are selling it, they should list the components. Their lack of details is making them look unprofessional.

Cyclo cross had gained a lot in popularity here, since I quit about 10 years ago. It is a very tough disciplin. Courses are designed to push participants to their limits of strength and aerobics.

No matter the buggy. Horses cost a lot of work and supplies to care for, can’t supply much work in a day, and even when they are not working they continue to require maintenance and food. They are also dangerous to anyone who is ignorant or negligent of their sensitivity, and very fragile to many en...

That is the obvious solution. Any other would be much more complicated, and likely less reliable. Find a Nexxus 8 spd hub with Shimano roller brake, your mother will love it.

The car won’t disappear anytime soon.

I will just assume that your 40 years of engineering had nothing to do with bikes. A DH race does wear components very fast, and shuttles are scratching them all at the same plsces. When a 5 year old DH racing bike has all its original components, original wheels and no shuttle marks, it shure was n...
