Nice bike ajax, i like it lots

 

Something you wont be able to tell from the photos is that the frame isn't round as you'd imagine, but flattened. The cross tube, for example, has a triangular-ish profile, flat on top, flat on the sides, and very funky. Certainly not an anonymous bike

Done around 120 miles on this bike now and it's good fun.

As they stipulate in the manual it isnt a proper off road MTB but it is perfect for trails/the road.

 

In terms of back up for parts...I think everything apart from the motor and controller is just generic bike bits....

 

I'm giving serious consideration to spending another £200 to upgrade the rear casette, hand grips, tyres and peddals as it's the fairly light frame ( with holes for wiring) that makes the bike IMO.

 

I do seem to be having a bit of an issue with the battery not charging all the way to 5 blocks on the battery strength indicatoe) but I intend to contact Burisch and see what they say.

My battery on the burisch does the same thing only four out of the five lights after a full charge ?could you let me know what they say thanks

I signed up to this site having read the reviews and opinions of this bike, was just about to buy one when the stock ran out. I've found that the guy behind Burisch is very responsive to questions via email and has confirmed that I can get spare chargers and a battery if needed so am impressed with their support. They did tell me that the new stock would be in for November and would have a couple of updated components but weren't very clear on whether that includes updated gearing and proper connectors for the controller... eager to hear what's coming.

 

Sadly I can't wait that long as I'm currently without any bike at all so will get myself a cyclotricity stealth to play with for a while. Pending further reviews from your fine selves may swap it for a Burisch when they are back in stock!

I've got the same issue... battery good for approximately 15 miles on the flat with some gentle hills, mainly throttle.

 

see http://www.pedelecs.co.uk/forum/electric-bicycles/12393-battery-charger.html

 

I'm beginning to think this might be down to the charger, as so many with the same apparent fault doesn't sound like it would be the battery.

I would also recommend a dab of Nut sealant for the crank bolts, as these with lower gears installed, are under higher crank preasure than normal and can work themselves loose.

Reply re Battery:

 

This is normal according to the factory, the LED indicator is setup for a range of different batteries, some of which are much higher output.

A fresh battery will show all the lights but over a short time the maximum lights it will show is 4 lights.

Hope this helps

 

Would be interested to hear what experienced e-bike users make of this...will there be an equivalent drop of battery capacity???

Battery indicator lights on most bikes show voltage; however, they can be set to whatever the manufacturer decides, and even then, there can be a significant discrepancy on indications, so I wouldn't take too much notice of them. They do give you an indication of how your particular bike behaves so that you can learn what's normal. Then you can see when you forgot to charge it or when the battery deteriorates with age.

 

If you really want to see what's going on, get a voltmeter like this:

^ Good answer thanks.

 

OK I'm on about 180 miles with this bike now and I've had a few more problems which it has to be said ; Burisch have been fairly quick and helpfull in their responses.

 

I had a loud repeating crank click/snapping noise which I reported to them so they told me to remove the crank arms and lightly grease the flat surfaces.

I dont have the tools to do this so I had to settle for a squirt of wd40 in the crank mechanism which seems to have temporarily solved the issue.

 

On returning yesterday evening I noticed the front suspension lock switch seems to have stopped working....leaving it unable to lock off suspension.

 

I'll contact Burisch about this and let you know what they say.

 

I hope this isnt a recurring pattern of cheap parts but as I said before...I've had a Dahon Jack that had roughly the same number of issues and didnt include any electric functionality so not too worried yet.

I think that's a serious contender and one of the best bikes I've seen for value.. 20.5kg including battery is very impressive for a full size bike.. although some might say 9Ah is not enough power or borderline..(but since the battery only weights 2.2kg you can always buy a 2nd to extend range). I think they have achieved a very discrete design though with the bottle battery and it doesn't look electric even at first glance.. great job, they're definitely tuned into what buyers want I think.

What I am curious to find out - and I have emailed Ryan with this question - does the 7 speed have a 14 or 11 tooth cog as top gear (if its 14 then thats no good) - and what chainwheel cog is he selling it with now (on mine the final combination that worked from any practical standpoint was an 11 tooth rear top gear and a 45T chainwheel).

 

Not heard back yet - we shall see!

Interesting question James and good point about the gearing..I agree anything less than 11T is useless if you want to pedal at high power.. I have a 11T and 52T chainwheel combo on my Mezzo.

 

I asked them and will post back, from the pics it looks like 14T. Being able to use a cassette certainly makes it easier and cheaper though to change gearing? That chainwheel doesn't look big enough though.

"- New 7 speed rear gear cassette and 7-speed shifter, for better cadence"

 

I think its almost certain from the statement above, that the new gears will starts lower than 14t, and i can't see a problem with them sourcing 11t.

 

Also the ebay link says the pics are for the 2012 version, and therefore wont show the 2013 'upgrades'. Speaking of which, i am seriously tempted now to fit rare discs brakes, but i don't have a clue on what's involved. Would this entail new rare wheels, or is there a simple way to adapt the existing wheel to discs?

 

Upgrades, don't you just love em.

Have a look at your motor on the oposite side to the gears. Does it have 6 screws in a circle with diameter about 50mm?

 

Yes. You buy a disk brake caliper and disk; remove the back wheel; screw on the disk; bolt the caliper to the frame mounts; connect the cable; reassemble the wheel.

 

No. You need a new motor, disk and caliper.

 

From the photos, the answer is no.

After i posted the question, i did some research, as you do. It doesn't have the circle of 6 screws you mention, however the motor does have an unused screw thread, I'm not sure on the size. But as you'll see in the photos, it is right where you would mount the disc caliper. It might also need some form of spacer to work.

 

I also found a disc which i think might work if the thread size matches. Now is it, or is it not 34mm?

Edited November 26, 201213 yr by Ajax

Well Ryan got back to me and he has indeed put an 11 tooth top gear cog on the back - and he's sticking with the 42 chainwheel. So thats pretty good.

 

It's the 11T rear that makes most of the difference of course - I still think it would be better with a 44T or 45T chainwheel - but I guess people can play around with that themselves - the most important thing is that rear cog - which was a bit of a pain when I had to change it myself on mine.

 

Maybe I'll get another one as a back up.......

Rear cassette is 11-28T and front chainwheel is 42T.

 

That's a good gear range, same as what I'm fitting to my Mezzo (the original is 11-26 which I would have preferred, but that's closest I can get for a freewheel).

 

I agree with James, 42T is too small, 44T would be better..the chainwheel on my Mezzo is 52T but then it has 16" wheels... and some some wheel bikers (like flecc) even like to go bigger! But this is a 26" wheel bike so maybe it works ok?

Just a quick word on the rear disc mounts. I decided to take a punt on the following::

Bicycle brake disc rotor 160MM with 6 bolts & Wheel Mount | eBay

 

It arrived the next day and was a perfect fit for the existing motor thread. Worth it for the screw on wheel mount alone, which is described as having an internal diameter of 37mm and is therefore [probably] not to be confused with 34mm you might see elsewhere.

 

I've now got manual rear disc calipers ordered [160mm], i just hope my installed pannier doesn't interfere with the caliper fittings. I'll let y'all know how it goes.

Edited December 1, 201213 yr by Ajax

As a quick follow up, the fitted rear disc "turned out nicely".

The panniers had to be fitted further up the main stem, but there's a hole provided for that.

 

Incidentally, the BURISCH are now back in stock. ;-)

BURISCH Synergy GT250 Ebike e-bike pedelec electric bicycle | eBay

I just bought one of these but made the rather silly mistake of not realising that they are limited to only 6mph in throttle only mode which is a bit gutting as I use throttle only most of the time. I have had an elecctric bike for 4 years which I use every day and that did 15mph throttle only so I assumed this would be the same but having read up on the law I think this bike has to conform to EU law cos of it's 250W motor and so throttle only is not allowed, whereas my old bike is conformed to UK law where throttle only is allowed. So for those not up on these things like me be aware of this issue as it's not made clear in the spiel about the bike on ebay or their site. So for now my lovely sexy new bike sits in the garage unused while my four year old battered £400 folder gets to fight another day until I can afford to get the controller changed on the Burisch.

eddie thanks for heads up on that,i was thinking of buying one ,like you i like to use throttle was wondering if ku 123 would work[as i have one spare i would use] maybee some tech guys on forum might know.

The KU 123 is set at about 32amps, which would melt that motor if you could get that much current from the battery, which struggles to provide enough current with the standard controller, so I'd guess that the power would cut every time you opened up the throttle. I'd get the KU65 from BMSBattery, which will give you three levels of pedal assist as well as an independent throttle - about £20 to £25 with postage.

Are you sure we are talking of the same bike? This bike new, can be used at its full 15mph speed in throttle only mode, a bit faster with the restriction disabled. I am referring to the 2012 model. You'll find glowing reviews from others on this thread which makes no mention of a limited 6mph on throttle.

d8veh thanks for that info ps if looking for place to go at easter in camper van try here ,great cycleing area, [would also be able to pick your brains ha ha]
