Re: Just more than a bike (low power / low consumption)

Well as long as you folks are talking "low power", you do realize that small front wheel geared hubs tend to work well as well. Less encumbrance with various gear systems as well :o

Re: Liberty Stealth Climber (MTB)

A good locksmith might be able to use a 'soft blank' to replace the key.
Or possible pick the lock and replace the cylinder.
Just a thought....

Re: These 250W ebikes (toys) are very popular

Rad Power Bikes have a good reputation. They also have some roving service trucks in major cities which means that they are one of the very few manufacturers that can actually provide service/replacement for their customer's batteries. Those are 48 Volt 14AHr batteries with fuses and a keyed switch ...

Every time I see this thing I think of the Kepler Friction Drive and his Youtube videos.
The thing that strikes about about those videos is the noisy high speed whining sound from the motor.

Re: 10kW, custom cut aluminum frame, QS205, full suspension

I also agree with bolts/ rivets and structural adhesive in gaps/ overlaps. Aston martins are put together that way and they are meant to go 200mph. The unibody for the original Honda Insight (circa 1998) was Aluminum with adhesive joints ( no welding ). Alas I never had mine up to 200mph :? It is n...

Simplest approach is to get an inline power meter. Something like a "Watts-up" however I happen to prefer a DROK like this: https://www.amazon.com/dp/B07FYHTBD2 Goes In Connect "inline" between your battery and charger when charging. That will give you how much power it has take...

That's true. As a season cyclist but a new e-biker, it spooked me at first. But because a slipping drive wheel still goes where it's pointed, it has never caused me to fall or lose control like a slipping normal front wheel has. I find a little help from the rider via the pedals can prevent most fr...

Re: Have built 3 rear-hub-drive ebikes......going to try front.

A bicycle usually has more weigh on the rear wheel than the front. So with a front wheel drive there is a tendency for the front wheel to spin when you are starting off and have low traction (i.e. wet grass or lose sand/gravel on a hard surface).
