A really light rear hub motor that you can throw a lot of amps into would be a really great trail bike, but if you want that performance for less than Grin prices it would be a mid-drive. I have a TSDZ2b and a BBSO2 and hands down it is the Bafang. Though my TSD is at only 36v, and the Bafang is...

Well, all I knew of trailer hitches was 2 inch receiver, or the smaller one. So thanks Curt for the edumacation. Yeah, I'd get the Class 3, 2 inch receiver hitch, but that would depend on the car on how it's attached. I would think a Class 2 hitch would be sufficient for 2 moderate weight...

He edited the post. I saw the 30 liters in the original post, but didn't think about it too much. I thought he must like his water. But in retrospect, that 30 liters is 8 gallons, and that's 60+ pounds on the back. So, definitely an order of magnitude mistake, though I had no idea when I first...

I think if I want to pedal fast that I'll stick with my $100 Roubaix. Fastest pedal bike I ever rode, though it's geared too high for my right knee. Decent pedals would cost more than the bike, and, as such, she sits an object d'art.

What is the voltage of the fully charged pack? That is what all the components need to be at, or under to be theoretically safe.

I ride with minimum assist and pedal like a cow chewing cud, but when I need to fight the beasts I do twist the throttle. I use my ebikes for recreation and transportation. It can be a life or death struggle with the cagers, and I seek to maximize my survival.

To each their own. I was riding my Trek 7.2 that I installed a Bafang mid-drive on and was going about 20mph when I hit a stretch of uneven pavement. I guess I wasn't paying sufficient attention, but the handlebars were almost ripped from my hands. Never had that sensation in all of my two-wheel...

I bought these two the other day. They are lightly used and long neglected. Knowledgeable people run away from twenty year-old full suspension mountain bikes, and you can get them for next to nothing, which I believe is what I've done . Now I'm saving up my leftover dimes and pennies to buy some...

I read about this feature before that's on the Grin controller installed on my direct-drive hub motor ebike. Today, I used the feature. When you go to assist level 0 the controller gives the motor a watt of power, and the wheel rolls without the magnets causing cogging resistance. Which means...

Have you taken it out for a ride. At that age I would be concerned about battery capacity (and function). I hope it all works out great.

Couldn't you do the repair yourself once you learn how to tig weld? I do fantasize about finding me a woman who can tig weld. I'm not having any luck. I guess all the good welding women are taken.

That sucks being in such an unfriendly location for bike riding. Generally, my community is very bike friendly but sometimes everybody seems to hop in their car and try to go somewhere quickly. Then I feel the fear from the risk of being crushed. And there ain't never no hurry in my town! Your...

I guess the bosch is just smarter than the bafang.;)

I just had a duh moment. I tried using the walk mode while walking my mid-drive bike off a ferryboat today. Man, that thing went too fast to comfortably walk alongside. And now I just learn to shift it into a lower gear for walk mode! Thanks Stephan! (though, admittingly, heretofore I used the...

This forum is so mild on the electric bike spectrum. On some other forums people the world over put upto,and beyond, 10 kilowatts into their motors. Thems is motorcycles. I gave up trying to convince people of the beauty of a bicycle. Some of us need some assist for our old broken bodies, and...

Wow, that's a steep battery price! You could have someone remove the cells from the battery case, ship the case with the bms and dispose of the cells. Then when you receive the battery case you could have someone reinstall new cells. The battery cells shouldn't be too expensive, but the labor...

Nice torque tool. And at five hundred it ain't all that much if you're working on a $8k+ bicycle. Though, I think I'll still do it by hand feel. I haven't stripped, or had anything loosen up in a long, long time. I even have a carbon fiber bicycle, I believe it's a 2007 Specialized Roubaix. It...

I, unfortunately, use feel on bicycles, though I would certainly use a torque wrench for a cylinder head on an engine. I have been turning wrenches professionally for all of my working life, so there is a fair bit of hubris there. I might be convinced to use a torque wrench on certain electrical...

A motorcycle's front brake is on the right because the clutch lever is on the left because the twist throttle is on the right. It has to be that way, or the opposite. I assume that on a bicycle the front brake is on the left because that's the British way of doing things. How you modulate front...

A good saddle is priceless. Though, I have put so much time on them over the years that most of them don't hurt too bad. Some do, and they just want to cause pain. So, I guess I'm lucky in that I can do twenty-plus miles on one of my free saddles on one of my free bikes and butt pain ain't a...
