The are some displays/controllers that custom firmware has been written for. I really doubt this is one of them.

I think there are other designs that could work better, but the real problem is the amount of weight that you want to carry. You may have to fabricate something from scratch. This one has a better design and is 16" wide, but only a 60lb capacity...

New York City seems to be cleaning up it's act, but I have seen pictures of shelves of batteries on chargers where the delivery riders would leave a battery charging while making deliveries so that they could swap batteries during the day. A quality battery is expensive and these delivery...

OP said he lives in a small apartment. I don't think building a concrete bunker is an option for him. There are over a million ebikes imported into the US every year. I think 1.7 million last year. Ebike fires are relatively rare. I found these interesting statistics on the People for Bikes...

I have those exact same grips on two of my bikes. Three if you count my wife's Electric Brompton. They're great.

"Embrace, extend, and extinguish" was a phrase that was found in Microsoft internal communications by the Justice Department when referring to open standards. You could argue that they have to make the system proprietary in order to optimize the performance, and that may be true to an extent...

It won't matter if there is one wheel or two in the rear as the distance from the axle(s) to the tongue will be the same. The only things that will affect the tongue weight would be shifting the load (center of gravity) forward or backward or moving the wheel(s) forward or backward. You can...

Here is an example with some assumptions, since I don't know the dimensions of the trailer: W : Total Trailer Weight (lbs): 225 lbs Laxle : Total distance from hitch ball to center of axle(s) (ft): 5 ft Lload : Distance from hitch ball to the center of the load (ft): 2.5 ft T=W(Laxle -...

I have no idea. I have never done it. You could try this:

Suspend the tongue with a fish scale. You can, of course just do the math. Formula for Tongue Weight T=W(Laxle - Lload)/Laxle T : Tongue Weight (lbs) W : Total Trailer Weight (lbs) Laxle : Total distance from hitch ball to center of axle(s) (ft) Lload : Distance from hitch ball to the...

That may not be possible. Some manufacturers have provided a feature to disable the speed limiter in the past, but laws have been passed in many areas like California, to discourage manufacturers from doing that. I would suggest riding the bike and seeing how you like it with the factory...

It looks like it might have had a mid-drive motor at one point and was converted to a rear hub. The frame is clearly built for that battery enclosure.

Order some spare parts and leave them with someone that can overnight them to a shop for you in an emergency. Finding someone to do the actual work shouldn't be hard.

I don't know how accurate that is though. The manufacture's web page shows this for the fork: Vaxa 100 mm fork. It doesn't give any details on the other components except the brakes are Tektro HD-M275 and the drivetrain is Shimano 10 speed. I'm glad to be wrong about the battery if they do use...

I agree. Most of my tools are Park or equivalent quality, but I bought a cheap headset press. I have only used it a handful of times since I bought it about ten years ago. It gets the job done.

Welcome to EBR! It should work for your stated purpose. It doesn't have a rack, but it looks like it has bosses to attach one. You could just use a backpack, but they get sweaty and uncomfortable on long commutes. For a few kilometers, it won't matter. It doesn't have lights, so you would...

Well, I wasn't really feeling like fixing the flat in the rain. I guess I'll just call an Uber.

If you have horizontal dropouts you can use that to tighten the chain. Some bikes have an eccentric bottom bracket for that purpose. Otherwise, they sell single speed chain tensioners. With the Gates drive, I have to believe the bike already has some way of tensioning the belt. Probably...

That looks like a good idea. I wish it was bigger though. You can charge and store up to a 2pc 6S 5000mAh equivalent (222Wh) safely inside the BAT-SAFE. Charging space: 9.5*6.5*4 inch / 240*165*102mm Outer dimensions: 12*9*7 inch / 305*230*178mm Weight: 4lbs / 1.85kg
