Hi Dansin,
Sorry to miss this thread, I spend a lot of time here in Mallorca and can't believe I've neglected my fellow tossers since this was posted in May, even letting my subscription expire!
Rest assured I think you found the best Mallorca has to offer to cover your needs this time. Anke and her husband Johannes do a great job. Since I met them 7 years ago the premises has doubled in size and the fleet of bikes probably trebled. As you will know they seem to have every variation of new BMW's (+ a few other makes) and the major advantage is the range of riding equipment, tyres, panniers and seat options available. Only downside is their slightly remote from Palma location in Felanitx but no problems if you have a car to get there (approx 40 mins from Palma). They cater mainly for German clientele and seem to be pretty busy all year round.
Glad you had a good day out, the trails and beach you rode to looks amazing. Those pesky pine needles will always find their way from the gutters if the winds blow! Goats, randomly parked tourists and crazy cyclists are the only other normal hazards.
On one of my rides out with Johannes I managed to push the poorly designed wanderlich gear shifter so deep into the gear box so far it wouldn't shift past 2nd gear, I jumped on his 400cc and he rode the broken 800 GS back to base remarkabley at a steady 100kph for 25 mins. Testament to the GS8, (I brought one shortly after). The oil was hence pretty warm when he dumped the sump leaving the technician to break the casing off and repair. I gladly handed over what was minimal euros for the trouble I'd caused and swore to buy the touratech shifter for my bike instead.
If you're ever looking for a simple rental bike in Mallorca I only know of two other companies, neither will offer the same level of equipment or tyre options as Mallorquin bikes. A keen biker will discover all Mallorca's best roads within 3 days although there's lots of opportunity to bomb the odd forest or trails if the tyres provided will allow to keep you busy for a week.
I've rented from these guys many times and their bikes always seem pretty tidy and well looked after. Closer to Palma.

Spotted this company a while ago as the rental costs seem a little lower, no personal experience though.

Drop me a mail if you ever head this direction again and want a ride out buddy or need Mallorca information, I come and go every 2 months, I ride a GS8 pretty poorly offroad and reasonably onroad but it doesn't stop me trying.
Regards
