Frog E-Bike Battery

$130 GBP
I have 2x very good e-Bike batteries. These have seen very little use and are only 12 months old, but have been kept trickle charged every month as lithium cells are better stored charged. Am selling as simply am not using my bike for longer trips as planned and have de-electralised it! (I used one as a spare, but spomeone locally wanted to use on 2 bikes so I bought a 2nd mount. He then changed his mind! The motor and other kit already sold) The batteries are 36v & 9 / 10AH 1 is the battery, under saddle mount and charger. Cost £250. Accept £130 1 is the battery and under saddle mount only, no charger Accept £110 Note I live in Highland, but for collection will be in Manchester evening 9th March near the airport, or alternatively as I'll be driving to France 25ht March I can drop to my friends house in Sheffield (Totley) or Leicester (Kibworth) where they can be picked up. I can post but would have to be via TNT as lithium and will take a couple of days to organise

Specialized Stumpjumper FSR, RARE converted to e-bike

$1500 GBP
Firstly I live near Skye, so whilst it may be possible to post I’d have to buy something to ship it in, which will cost & may be tricky (suggestions welcome). Also I’d really much rather you try it first to make sure happy  Best to message with any questions Then we can exchange email addresses - mobile is cr*p where I live & Pinkbike ask email addresses not to go in the add text due to spammers. The bike is a 2006 Specialized Stumpjumper FSR, fully serviced & converted to e-bike with two batteries. I am selling as just not using enough to justify it’s value. I think it gives the best of both worlds. The bike first. Note the front and rear shock travels are estimates, I will check & update later. It is medium, 27spd. I am 5’11” and find it fine - I have the saddle taller than normal due to have knackered knees so my feet actually don’t touch the ground! It is 26” wheel, and although an earlier Stumpy, less than 200 miles ago it had all pivot bearings replaced, new Hollowtech bottom bracket, new headset and general service. Within 300miles ago also had new Sram PG980 cassette, new matching chain and middle ring replaced on the chainset (all matches & doesn’t jump). The frame inevitably has some scuffs and scratches as is normal but is entirely sound with no cracks or damage – I ride cross country and am too old to thrash it down gnarly downhills! Mech’s are XT and good, crank is Hollowtech. Shimano rapidfire shifters, the plastic ‘windows’ on the changers are inevitably scuffed and scratched but you can still clearly see the gear selection indidcator (not that I ever look at as you tend to know what gear you are in), cables are stainless and entirely Teflon lined cable tubes (no exposed cable). Brakes are Hope mono hydraulic and good (expect them to squeal until bedded back in, as only ridden literally a couple of times this year!), they were serviced with new pistons not long ago and I find very effective. Front forks are Fox Float 32 & rear shock is a Fox Float RP32. Mavic 717 on the front and Mavic 317 on the rear, rims are good and true. Kenda tyres. Any questions please ask Now the e-bike bit. I had it custom converted about 18 months ago by a private engineer aquaintance, and it works really well. The sensor ring was custom adapted to work with the Hollowtech bottom bracket as most kits supplied don’t. This meant I could keep the FULL Stumpjumper spec as didn’t want to lose that – in fact take the battery holder off from under the saddle and put another rear wheel and cassette on and your back to a ‘normal’ lightweight Stumpy, the rear wheel spacing is entirely standard. It has the usual settings of 1 – 5. Setting 1 will assist progressively up to about 7mph – pass 8mph and you do 100% (literally) of the work yourself. This follows the same pattern through all settings, the top one assisting to approx 20 mph above which as before you do it yourself. I tend to leave it on 1, so means I am riding as normal doing all the work’ myself, but if going up a steep hill then obviously slow down and the assist kicks in. (Occasionally if caught in a heavy rain shower have been known to wack it up to 5 to sprint home as quick as poss  ). The batteries are Frog batteries, and very neatly fit under the saddle like a saddle bag – I think they are much neater than the huge tube on the frame that some have, and for that matter much less obvious. In fact apart from the larger rear hub (that has the motor in) you don’t really know it is electric. I like that . I bought a second battery at the beginning of the year, both are batteries contain Samsung cells, and both battery packs are only about 12 months old, have been kept topped up (the correct way to store Lithium cells) and I know are very good – these alone are £200 - £250 each. With the two batteries this obviously gives the bike a very good range. Note a voltage is displayed on the controller, I only ever drop them to about 3.3v – it is NOT good to drain litium cells completely as this will ruin the battery and they won’t recover. One thing to note, the motor unit on the rear wheel is water resistant and splash proof, and fine for normal use (even up here in the Highlands :-), but note it is NOT designed to be submersed. Therefore do not jet wash or hose the bike the rear wheel. I tend to let muck dry and just brush it off, and then give it a wipe down after.
