I did notice that the solid axle has a taper towards the middle of it. Not sure if they were try to save some weight. I wonder if a replacement axle without any taper would help?

Pulled the wheel; tighten the hub some, but it didn't help. John

I have rubbing noise coming from my disc brakes. The sounds comes and goes. Had a friend look at it and noticed a lot of play left to right in the rear wheel. Checked and it is correctly tighten, but noise comes and goes. We believe I might be because of the rear suspension movement...

During last years (2019) model clearance picked up a LT ($2499) but also saw the non-LT ($2199). I read that LT stands for Long Travel, but not really sure what that means. Can someone explain the differences between the LT and non-LT Haibikes? Thanks, John

Got a flat rear tire loosened the hub bolts and the tire still isn't coming out. Do I just give it a good pull? How does the wire going into the rear hub disconnect. John

You are brilliant!!! The bike is new but I am 6'5" so as soon as I get a bike I have to modify it before I can ride it. I was trying to put a taller stem on it. You can see in the below pictures that the new stem did not provide enough gap for the compression screw. I put the original stem...

Just got my new bike. There is a lot of play in the headset. I've tried re-tightening it several times. Never can get rid of the play in it. How far can I tighten it without damaging any parts? Is there a torque setting. Tried many of the ideas on YouTube. Nothing has worked so far. Any...

Easy question. What size quick release do I need for my seat post? Specs say my seat post is 31.6 mm so for the quick release would I want a 31.8mm? Thanks, John

Apparently my bikes (Yes I have two of these) were put together with the wrong screws. I need the correct screws for the upper battery mount that attaches to the frame. I believe they are as follows: ST 2.6x16 M 3x10 ST 2.9x13 If ST stands for Self Tapping it might be better to have a wider...

Had a friend look at the bike yesterday that chain was not stretched. However, my bike is an XL and he looked at the derailed and believed the chain should be longer, so we replaced the chain with a chain that is two links longer. In addition, we replaced the cassette with a higher quality...

My bike seems to be experiencing a similar problem. It seems to skip when pedaling with lots of tension on the chain. I think I'm gonna have to mount a Go-Pro (look alike) back by the sprocket to see what is really happening.

Help!! I put Schwalbe Marathon Pro 29 x 2.10 on my AlexRIMS MD21. It appears as though the tube push out the tire and then the tube exploded. These tires are 54mm wide and according to the tables should be fine on my MD21s. Any thoughts on what might have happened and how to correct the...

Thanks!!

I'm trying to replace the tires on my Hai Bike 2008 Cross with something more durable and aggressive. I understand tire width and what the rims will accommodate, but don't understand tire size. Which I guess is diameter? The RIMS are 622x21. What size tire should I purchase? Thanks, John

Thanks!!!!

Received the Moscow Plus in the 29” and ordered another in the 27.5”. I actually prefer my mid drive bikes but I can’t pass up the price/value of the Moscow Plus. My mid drive cost $3K and the Moscow Plus is about $1.5K. I have extra bikes so when someone visits me they can ride along. I’m...

What charger do you recommend for a Dehawk 48v 16ah battery? Where can I buy one? I’m in the US. This is the battery used in the Moscow plus bike. My existing charger seems to have died. Thanks John

I have Alexrims MD21 on my cross style E-Bike. I've been taking it down mountain bike trails and would like to install wider tires. Can anyone tell me how wide I can go with these rims? The current tires on the bike are 42-622. Thanks, John

Appreciate your reply. I have the Moscow Plus arriving tomorrow. I was going to have to wait until mid August to get the larger battery pack for the Shred. The price on the Moscow Plus was just too good to pass up. I’m looking forward to seeing how it performs. Thanks, John

I’m looking at picking up my third EBike. I have two mid drives and now want to get a hub drive for people to ride along with me. I’m looking at hub drives because of the lower cost plus the throttle capability. I’ve read/watched the reviews for both the Moscow and the Shred, curious your...
