We felt that we needed a bit more affordable model in our range of Expert line of bikes, so we changed a few specs without sacrificing strength on the 2021 Electron. We are using the pinch bolt style cranks we used on previous versions of the Electron that we had no claims on, a thicker steel Trebol sprocket and 2-piece steer tube forks. Three details that add a bit of weight, but keeps the strength that we wanted, while cutting the cost of the price of the bike. The Electron is a great mid level bike with a lot of aftermarket parts like Devon grips, Ruben pedals and a Trebol fully sealed rear Cassette hub, double sidewall rims, Trebol tires and a sealed headset. One request from distributors and customers was to have this bike available in a 21” version for the taller riders, so that’s exactly what we have done.Geometry:TOP TUBE LENGTH- 20.5″ / 21”CHAIN STAY LENGHT- 13.2”HEAD TUBE ANGLE- 75ºSEAT TUBE ANGLE- 71ºBB HEIGHT- 11.5”STAND OVER HEIGHT- 9”FORK OFFSET- 27MMBAR RISE- 8.75”BAR WIDTH- 29”BAR BACKSWEEP- 10ºBAR UPSWEEP- 2ºSpecs:FRAME- 4130 CRMO DT / 1020 HI-TEN / WELDED PIVOTSFORK- 4130 CRMO 1 PIECE STEER TUBE / 1020 HITEN LEGSBARS- 1020 HITEGRIPS- FLYBIKES DEVON / 160 MM LONGSTEM- TREBOL TOP LOAD / FORGED / 6061-T6 ALUMINUM / 50MMHEADSET- TREBOL / INTERNAL SEALED BEARINGLEVER- RIGHT / DIE CASTING ALLOYBRAKE- TREBOL SPRINGHANGER / FORGED / 6061 T-6 ALUMINUMCRANKS- 3PC / 4130 CRMO / 170 MM ARM LENGTHBOTTOM BRACKET- MID / SEALED BEARINGSPROCKET- TREBOL / HI-TEN STEEL / 25TPEDALS- FLYBIKES RUBEN GRAPHITE / NYLON – FIBERGLASS COMPOUNDCHAIN- 510 TYPE / 70 LINKSRIMS- TREBOL / DOUBLE SIDE WALLED / 6061-T6 ALUMINUM / 36HFRONT HUB- ALLOY SHELL / LOOSE BALL / 3/8” MALE AXLE / 36HREAR HUB- TREBOL / SEALED BEARING / 14MM MALE AXLE / 36H / 9TTIRES- TREBOL 2.35 FRONT & REAR / 60 TPI / 65 PSISEAT- ELECTRON COMBO SEAT / 100% SYNTHETIC LEATHER / 25 MM THICKNESS.WEIGHT- 11.3 KG
