    Bike Chain Replacement

    Hello everyone (my apologies for not being active more. However I enjoy reading other's post.)

    I ended up buying a R model ebike from Electric Bike Company (EBC) with a few upgrades...total cost was a tad over $3000. The look and quality of the bike is great. Where it fails is the battery as after upgrading to a 14Ah so as it could get up to 70 miles on a single charge. However a month after purchasing on a mostly flat bike trail with some but not an excessive amount of hills and being 5'9" 190lbs, it has never achieved more than 20 miles on a full charge. To me this is unacceptable! As we know the battery is the most expensive part of an ebike. I would not recommend Electric Bike Company (EBC).

    Okay, my question...the chain fell off and EBC informed me that it was a 57½ inch length. Can I please get help on where the best place to get a replacement (online or shop)? I was thinking of buying online (Amazon's prices seem low) and having it replaced at a shop. Can I get some advice on the best way to approach this? Thanks in advance

    Chain fell off? Just once? Or it keeps falling off now? We may want to dig a little deeper into that. How many miles on it? And were those miles mostly clean(ish) or was there some rain or worse yet salty winter conditions involved?


    Hmm..... reading their specs I don't believe even half of em and it sounds like that has been your experience too. Also looking at the price it seems like they are possibly double what the actual specs/performance is. I don't know that much about hub motors but in the pictures/renderings those don't look big enough to be 1250 watts. Their ranges would maybe be possible for 250 watts but I can't see anyone getting that from a motor that can draw 1250 watts especially on a hub motor where you don't have gears to shift though to keep the motor running at its most efficient speed. Looks like its also got to be quite a beast to pedal. Says its a 56t up front and 13 in the back. With 26" wheels? Dang, that is more the combo you would see with 20" wheels.

    Chain they don't say anything about other than 'stainless steel'. This means we are not sure if its a 'single speed' chain or maybe a mulit speed. Can you take a picture of it fairly up close and post it? Single speed chains tend to be made up of very flat plates. They are basically totally flat figure 8's pinned together. Single speed chains don't have any side to side flex and don't intend to have to change gears. Multi speed chains which in 5-7 speed style often will work on single speed cogs will allow for some flex side to side and are able to deal with slight miss alignments. They also tend to have more complex plate designs with angles and bends to them to allow for gear changing.

    To 'cut' a chain off the bike if it doesn't have a master link or re size a new chain you need a chain tool. The Park one I linked below is a nice quality tool that is compact enough to carry on your bike for emergency roadside repairs but is strong enough for semi regular use. Its under $20 too so likely cheaper than a shop would charge you do to the job. Basically its a little press that presses the pins out that hold the chain together. It can also press them back in if its the type of chain where that is the recommended practice or the type where you can buy replacement pins. Many cases these days people just use master links often called quick links.

    The master links depend on the chain type and have to match the chain type. A single speed uses the type with the clips. A multi speed uses the types where there are just 2 parts that snap together. All I have been running on my E bikes is quick links. I think Quick Link may be Shimano's brand name. I'm actually running KMC missing links. Those just snap in no tools needed for install. Sometimes getting them apart needs a tool but it can be improvised if you don't have one of the proper tools.

    If you get us a pic of your existing chain we can likely help you pick out a proper replacement and the proper link for that style of chain.

      A hub motor bike shouldn't be too hard on the chain. A quality stainless steel chain from Wippermann is a very expensive part. I think a nickel plated chain from a good brand, KMC,SRAM might be a better choice. KMC is strong and affordable in case you need to buy a new chainring and or sprocket also.

      For chain maintenance I would add Squirt wax based dry lube. It stays where you put it better than grease types, and doesn't pick up as much sand.

      And a chain checker. A worn chain can wear the cogs also. If the new chain doesn't sit all the way down in the sprockets then they need to be replaced also.

      I would suggest learning to do this yourself, and keep a spare chain around. Lube often and replace the chain before it wears out other parts.

      My advice for a 1500W BBSHD mid drive would be quite a bit different.

        The chain fell off while riding. On the way to the shop it slipped out of the back basket and I have no idea where. It's a single speed. A search for 57½ inches and converting to ⅛ inches that didn't help. Seems most chains are based on number of links and when I did the math for ⅛ inches (search showed this is majority measurement of links) from 57½ inches, the number was off. Math isn't something that I'm good at even with Google. I just want to buy a quality chain and have the shop install it. The local shop will overcharge for the chain without a doubt.

        I hope this helps. What if I get the longest single speed chain, could the shop resize? However it will probably alert them it isn't the original. Should I care?

          From what you've written: Stop, you're not mechanically or electrically skilled.
          EBC builds an excellent eBike and battery pack, why diss them here ?
          1) Why don't you charge up your battery ?
          2) Pay for your chain replacement and proper installation & bee happier.

        Not all shops will install parts you bring in so you may want to check with them before you buy one and bring it in. Price wise for name brand stuff shops are going to be pretty close to online prices. The bigger brands have pretty strict policies when it comes to pricing on current parts. You do sometimes find someplace that has open box or closeout stuff cheaper than maybe a shops price that bought the part when it was current but in general pricing is going to be pretty close. I'm not sure what the current crazy shipping costs have done to that puzzle, its possible that recently received product will be more expensive because shipping costs have gone nuts.

        That pricing control thing is why you see so many stores that sell bicycles and bicycle stuff having some sort of membership club where you get a rebate or discounts, that is a way around or allowed by the manufacturers. May be worth asking if your local shop or store has a membership deal like that, mine does. It cost like $35 to join and I get 10% off all the time and 20% off one item per month. When I joined I was buying a $350 pair of boots so it was a nobrainer to join. The discount on those more than covered the membership cost.

          The links you are talking about are 1/8" wide but 1/2" long so 57.5" = 115 links (+ connecting link)

          Frankly chains at the shop are going to be silly inexpensive (<$20) so I'd just buy it from the LBS

          I just went through this with a friend that desperately needed a new chain (the old was going to come off) and she bugged me about what to order online and I just told her to go to the LBS and tell them what you need and I'll put it on for you... she left with a $12 chain... five minutes for me to install...

          It's typical to get a chain that's longer than what you need, it takes about 5-10seconds to shorten with the proper tool - OTOH 116link (including connecting) is a very common size sold

            FWIW

            On my own bike if I go 20+mph and don't put a lot of pedaling effort in, 20mi is going to take close to that 14Ah and you don't really get the max capacity of the battery regardless since they'll generally shutoff before getting all the way down so they last a lot longer - running them to zero is hard on them and will reduce their overall life

            OTOH I can pedal my bike at close to 10-12mph with the power turned off and will essentially get infinite miles on a charge like that - I do this when riding with friends on their non-electric bikes

            Having said that to get 70mi on a 14Ah at much more than 10-12mph will require a mix of pedaling hard or not going fast... I pedal pretty hard most of the time and will typically get 40-50mi on 14Ah if I keep it around 15-17mph... but like mentioned speed will really run them down if I'm running 20+mph and still pedaling hard I might only get 20-25mi although that's uncommon for me since I'm not usually going that fast all the time

              Thank you to those that have helped. Especially AZguy! My original post was stating the fact of my experience. I did have a bit of knowledge from having the trike built as I had to rewire and solder with an upgrade. Never needed to petal the trike as the petal assist couldn't be installed since the pre-assembled frame was unable to remove where the sensors went.

              The reason for purchasing online is because I want to get either red or black chain.

                You never know what a shop may have in stock and depending on their location some shops get daily shipments from suppliers. Weekly for sure. I think colored chains are popular with BMX which is single speed so there is a decent chance of them having stock. I don't think BMX had as big a boom as the rest of the market so even better chance of finding stock.
