Hello everyone I have the Bearprint New City 505 E bike which I bought in October 2010 and you might have seen my review for it in the review section. I am posting an update about some problems I have been experiencing.
So far I have done over 4500 miles commuting to work throughout the winter and into this summer.
Overall the bike has performed very well with few problems until recently when it seems going over 4000 miles has been the trigger for several problems to occur.
The power started to become intermittant until eventually it failed to give any drive at all.
I checked the battery contacts and visible connections and cleaned out the controller box under the battery and reterminated the plug connections and sprayed with WD40 to give good moisture free connections.
This temporarily resolved the issue but after a few days it happened again.
Steve and Phil at Bearprint sent out a replacement controller which I fitted myself and this fixed this problem.
The next thing to go wrong was the battery fuse which blew going to work one morning, I managed to make my way without power - which was very tough - to a garage on the route who checked the fuse and said it was a 16 AMP type, I bought two and fitted one with one spare. About a mile up the road on a steeper section the fuse blew, I fitted the spare which also immediately blew. I made my way back to the garage and after a phone call to Bearprint eventually I was advised that a 30 AMP fuse was needed and while I was unable to obtain this the garage and a car parts shop near my home were able to offer a 35 AMP blow 17 amp continuous fuse which seemed to be able to handle the electric current ok.
Shortly after this I booked the bike into my local Bike shop for a service as it was overdue with the mileage I had done and there were some things needing attention:-
1) The crank bearing occasionally was making a "grawnchy" noise.
2) One of the rear wheel spokes had lost the tightening nut which had fallen inside the wheel leaving the spoke loose.
3) The water bottle holder had become loose even though it has never been used to hold a bottle.
4) General servicing inspection all over.
Strangely on the morning I took the bike to my Bike shop just a hundred metres or so away from my home I noticed the pedal assistance was not working while the throttle was ok. I tried wiping the sensor and magnet plate to ensure there was no dirt or obstruction and it seemed to work again.
On my return from a weeks holiday in Cornwall with my family I collected the bike with it's new sealed crank bearing fitted and noticed that the sensor again was not giving power while the throttle was.
On checking the sensor it was broken with the securing screw part having snapped off some how - I have no idea how this may have happened.
Thinking back, on my last trip back home from work before my holiday I thought I heard something snap or ping off and momentarily paused and looked back and around for anything which may have fallen off the bike but was unable to see anything and I was able to carry on home with no problems .
Phil at Bearprint kindly sent out a replacement sensor and another controller just in case and I managed to fit the new sensor which resolved the issue.
This was not as easy as I had hoped as the retaining screw is on the right hand crank side and is covered by the chain cog and pedal. I purchased the necessary tools to remove these items and fitted the sensor.
If the retaining screw was accessible from the left side under the crank housing it would have been much simpler to replace the sensor.
Everything I hoped was going to be fine but when I wheeled the bike out of my conservatory for a test drive a piece of the battery bottom plate fell onto the floor. This plate developed cracks quite soon after I had the bike and I had mentioned this to Bearprint previously.
I removed the battery and the 2 pin plug pulled out of the bottom plate as it was no longer held in postion.
I will attempt to post a photo below showing the broken plate:-

Currently I feel that I have been unlucky to be getting a series of problems one after another which are preventing my enjoyment of the bike. In particular I want to carry on commuting to work with it and have been getting "withdrawal" symptoms at this enforced off road period of 2 weeks while I have been on holiday.
I phoned Bearprint again this morning and was advised by Steve that he had never seen another instance of this plate breaking and that they would have to charge for a replacement plastic plate into which the connector plug fits and onto which the battery seats.
Naturally I was unhappy at this and I argued that this item should be covered by the warranty which was listed as 2 years for electrical items and 6 years for the frame.
Thankfully Phil phoned back to advise that they would send out a new plastic plate and that it will be covered by the warranty.
With regard to the crank bearings giving up the ghost Phil advised that he has known them go after just 2 thousand miles, I have no experience in these matters but that does not seem like much of a lifetime for a new bearing.
What sort of mileage should a new crank bearing give before it needs replacing?
I was happy to look at this particular repair as being my responsibility under "wear and tear" was I right?
Well that's it for now I want to give an account of my experiences with the Bearprint bike so other forum members can way up any pros and cons when looking to purchase bikes themselves.
Obviously I have a £1200 vested interest in my own bike but I believe I can be impartial and can stand back and try to give a neutral view of events as they unfold.
Like everyone else I have noticed members opinions of the Tonaro bikes and if I had seen these before I had purchased my Bearprint bike I think I may have bought one of these instead.
In particular their crank drive system may give better hill climbing ability and also less drag when being used without power. Also the battery replacement costs seem good when my Bearprint battery is likely to cost over £500 when eventually it expires.
My hub drive Bearprint while it freewheels well when going down hills, etc, when cycling without power there is very noticable "drag" which makes it much harder to cycle - in fact I do not want to cycle it without power.
To be fair a powered bicycle is designed to be used as such with power but in an emergency situation those which unpowered feel more like a heavy unpowered bike will be nicer to use during any "powercut".
Best wishes to all,
Barry.
