spare speed sensor (easy to snap off) spare throttle (notoriously bad) Possible spare controller but you can probably get one shipped to you fairly fast. programing cable If you want to go deeper than that then you need the special tool to remove the axle nuts to split the case. You would also...

I went out this afternoon to run a test to see how much range I could practically get. I decided to shoot for and average speed between 12&13 mph on a 20 mile loop. Wind was around 10 mph and climbing is just about 1000'. The bike gross weight was right around the 290 lb mark. I figured if...

You make an attachment that bolts on where the three cap screws are that replaces that piece and includes the hitch. You also have enough axle showing to make something off from that

My trailer is the QuietKat trailer but it's highly modified. It was lowered 2.5 inches and the hitch is full ball bearing. The center of gravity was too high for good bike handling. I still have pretty good clearance but I can double the load now and have better handling. I can modify anything...

Oh I might be either this or Great Divide Mountain Bike route. I am in North East Ohio and have my bike set up for long distance unsupported travel.

The highest I have gone so far is 175 miles with 30% useable remaining but I have a 52 volt 49 amp hour battery bank. Given chargers, battery age, battery temperatures and battery sag I can count on 70-75% of rated watt hours at still be at 45 volts. or 25%

One more tip: I do a lot of off road biking in the snow on my e fat bike. Tire pressures 2-3 PSI on tubeless full studded Wazia 26X4.8" tires. When the snow get up to the motor I lower my seat post and put my feet out to the side and use the throttle. Pedaling in deep snow upsets the balance...

I don't have that kind of a readout in my information but let's just say that I was going slightly downhill with no wind in the lowest setting and still pulling 90% of the power for that setting. My speed would be right around 19.8mph and the the battery happened to start at magical 100%. The...

This is an old thread but I have some recent data. I was sitting on a picnic table 7.5 miles from home with 480' of climbing when the phone made the defcon 1 weather warning giving me just 20 minutes to beat it. I have a high windage fat bike with big 52 volt batteries with BBSHD drive. For...

Not knowing the OP I was trying to be serious. The BBSHD will not install upside down in the Blackborrow and the downtube is sloped to near zero so you cannot roll it up out of harms way. I would not consider the CYC for that application. I think of the CYC as being for very knowledgeable...

Bingo, I somehow overlooked the obvious with the throttle voltage.

What is very important with a Hailong battery are the two little slots at the back of the battery. Those slots must be engaged or the front tabs are in danger of being shattered. The front tabs may be holding but if the battery is not installed far enough to engage the rear slots or, the battery...

Your chainline probably sucks with that chainring. Expect pretty low chainlife You might consider reprograming your controller to have smaller power increases at the low end and bigger jumps at the high end. I comes from the factory with 10% increases in power. I programed the first jump at...

I strongly considered this bike but it is not a candidate for a mid drive conversion due to the motor having to hang very low under the bike. Too bad the frame is not offered with a G510 Bafang mount. The bike is a candidate for a hub motor

Let the air out of the front fork and fully depress it to make sure you have clearance before you commit to this installation. Hailong battery boxes are notorious for breaking tabs. Secure it with good straps.

True Panasonic battery cells are good cells but you battery capacity is likely not high enough.. Got to cut costs somewhere. I also suspect that you are using high power for too long at a time. The Chinese version is likely not duty rated and you are experiencing overheating problems in the...

The problem is likely the battery capacity and the bike is operating normally. Batteries work by chemical reaction. As the reaction takes place the atoms for the reaction have a harder time finding other atoms to react with because of the newly formed molecules that are in the way. As that...

If QuietKat ships overseas you can get everything you want in one bike. I have ridden one and they are high quality.

I just took a couple of flat screw drivers and levered them under the bearing as shown in your picture. The bearing popped right off with some effort.

Why on earth would you want torque sensing for that application. Torque sensing turns a bicycle into a primary exercise machine. A western world thing about bicycles primarily being for exercise. No way in hell would I want to deal with steep hills, two jumpy kids and groceries on an exercise...
