Continuation of Veganarchy's review..
We have taken the bikes out for a long range test set at 30% power with the assist going up to 11mph just to see how far we could possibly get on a full battery with low assist. We were mainly riding off road on tracks and bike trails, lots of fairly steep inclines and hills. The LCD screen stated 100% battery constantly until we reached 35 miles, only then it started to decline in percentage. The bikes actually managed just under 100 miles altogether! One of the main things that nearly put me off buying the bikes in the first place was the stated range of 45 miles with pedal assist. I know there any many things that can affect the range like user weight, wind, tire width + pressure, your own physical effort, assist level, terrain etc. I still think Merky have sold themselves short and have been a bit too conservative with their stated range though and I hope this has not hurt sales for them. Most if not all other companies state huge numbers for the range of their bikes that are only achievable under absolute perfect conditions so in such a competitive market I would advise Merky to do the same. For comparison our old bikes with a 10AH battery were stated at 40-100 miles range per charge and could only reach around half of what the Merky bikes can achieve at almost identical assist settings. I am pretty sure I could have travelled quite a bit further too as the conditions of our test were far from perfect. With this in mind Merky could easily state 45-150 miles or even more imo.
Advice for anyone who owns this bike -
To increase longevity of the battery try to keep it at around 70% charge and avoid leaving the bike fully charged or completely flat whenever possible. To achieve this, charge the battery until the LCD screen only just reaches 100% and then stop.
Buy mudguards for the front and back as you do not want stones chipping your paintwork, mud covering you and the bike or water getting inside the suspension pivot and causing rust.
The kickstand became loose on both of our bikes so I would check that before the bolts come out while riding and are lost forever or worse. I took the bolts out and put Loctite on them to prevent this happening again.
Another thing I did was to take the cover off and check the wires and speed controller. Do this at your own risk but I am glad I did as one of the plastic sleeves had moved right down the wire leaving a huge metal contact bare. If this happened to another wire and they both touched each other I should imagine it would have been bad news for the bike.
I would leave all of my battery saving settings on here as well but this review is already insanely long so good luck finding what works for you!
Update -
One of the rubber seals on the rear shock snapped and I noticed a crack in the plastic cover where the mid drive would be in the same place on both bikes. These problems are no big deal as the parts are cheap plastic and rubber but that is also exactly why they broke in the first place. Using cheap plastic parts on bike frames is obviously not a good idea. I have looked everywhere online and can not find replacements so I have no way of fixing them myself in future. Still waiting for Merky to get back to me about this.
WAY worse than this is how the hub motors are attached to the frame. The frame is DEFINATELY NOT designed to have a hub motor for a start. The bike frames are mid drive frames. The axle only just fits into the frame, it does not fit snug and the safety anti-rotation washers are both pretty much useless as they are hanging outside of the dropout. The frame on my bike is already being chewed away by the axle because it can turn freely inside the dropout. These bikes do not come with torque arms which are essential on motors of this size and power and there is actually nowhere to attach them even if you try to do it yourself. There are no screw holes on the side for panier racks, fenders or brakes so nowhere to attach torque arms. In my opinion this bike is NOT safe to ride.
I advise anyone who owns this bike to do your own research, take your rear wheel bolts off and check your safety washers. If you are mechanically minded and understand what their purpose is, you will instantly see why this is a BIG problem. The axles could eventually chew through the dropouts and then the best case scenario is that your wheel loses all power as the axle can turn inside the frame instead of the wheel turning. Worst case scenario is that your dropouts snap while you are travelling at speed. I really hope this is not a possibility but I can already see the damage being done to my frame by this terrible hub conversion and I have only owned the bikes for a month or so.
I have sent photo's of the damage on both bikes to Naomi and the tech support guy. They have both chosen to ignore me!
I would not buy a Merkybike unless you are a mechanic and willing to repair and replace parts at your own cost.
