Have just completed a conversion to a 1998 GT FS bike, using a Bafang BBS02B 48v 750w, and from the amount of space in the triangle it looks like you could fit the usual shark style battery on your downtube. Check first to match any kit with your bottom bracket width AND chainstay clearance...

Mine are a work in progress, having found like others, that the hydraulic sensor system is finicky, especially with unsuitably shaped levers and brake bodies. Lever travel is the biggest issue, however my Avid Juicy 5's have an extra click stop that adds to the distance, sufficient for it to...

Have taken up your suggestion and purchased a Lekkie 42T (not cheap at A$175); I also decided to ditch the existing 9 speed 11-34 cassette for a 10 speed 11-40, that I had. Also then have had to order a matching 10 speed XT shadow clutch rear derailleur (said to improve hang on ability), 10...

Yep, although if you shop around, you might be able to upgrade to 48v/ 750w for the same or similar cost.

For off-road as well, you will only be happy with a mid mount, however for that money you should be able to match the latest Bafang BBS02B 48v 750w kit to a suitable second hand full suspension or hard tail. You will need some tools and basic skills ie the ability to think around issues, but if...

I bought both sockets, as I already had a big torque wrench for bottom bracket removals / fitting . Bafang sent me their basic instructions when I asked and I did find a setting for the lock ring, which I think from memory ranged from 36 NM. I have ordered a spanner but in the end was not...

I have discovered the same problem with the cover and the lock ring, although I thought Bafang said the BBS02 was suitable for both 68 and 73. Anyway having purchased a lock ring socket from Luna Cycles, and with it torqued to at least the spec, I have just been able to get the cover to thread...

When I was younger the idea of 70 year olds on bikes was weird. Now I am one amongst a group of at least 50 ( we are all ex-servicemen), of at least that age, the taunts we receive as MAMILs are easily rejected, because we are in fact past middle age !

Another issue is that rear wheels with hub motors are a pain to remove, whereas a mid mount gives you more flexibility, in terms of ease of transport; punctures notwithstanding.

Well now, I'm one of you; in the sense that I am plus 70, with a heart condition (recent stent) and live in a hill bound location; eg have an 18% round the corner. Having also put on a bit of weight, I have made a gradual transition from a sprint (CAAD 9), to CX (CAADX), to a 36v pedal assist...

Cheers I gather you are suggesting that it might be better to move the chain line inward (aim being the centre of the cassette). For the Lekkie, I gather the offset is 4mm more than the stock, so it may still clear the chainstay by the said minimum recommended of 3 mm; otherwise I wasn't aware...

Further to old school mid mount clearance issues. With supplied 44T chainring, it appears to line up with about the second or third smallest cog, out of the 9 on this cassette. Given the stock chainring is only about 1 cm away from the chainstay, the bigger offset of a Lekkie may be a problem.

Webbing looks the same and its being wider was my concern, subject to the diameter of the closest chain ring.

Thanks for your assistance; width measured at the front pivot is just under 70 mm

It gradually widens further back, to about 100mm, however at that width it is beyond the reach of the current chainwheel. Found this estimate on a thread looking at chainring diameter and without undertaking the math, viz tooth size and spacing etc. 28T = 116mm 32T = 132mm 34T = 141mm 36T =...
